Objections to the Claim That UFOs Are Demonic

For more context and for the individual arguments supporting this claim, please see the answer to this question: Question 98 — What is Christianity's view of the UFO phenomenon and extraterrestrials?

Here I will mention only one particularly telling argument: abductions and tormenting experiences are, to a significant extent, brought to a halt as soon as the abductees call upon Jesus Christ for help. These beings evidently respond to the name of Jesus and fear Him. There are also testimonies of people who were repeatedly abducted for years, but after turning to Jesus Christ, these abductions stopped. In practical terms, it seems that the only effective defense against these beings is Jesus Christ Himself.

A few examples — not the only ones — from the Bible: 

• "Therefore God has highly exalted him and bestowed on him the name that is above every name,  so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father." (Philippians 2:9–11).

• "The seventy-two returned with joy, saying, "Lord, even the demons are subject to us in your name! ... Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you." (Luke 10:17, 19).
• "For by him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things were created through him and for him." (Colossians 1:16).

Although, in the context of authority, this is a promise given to believers, it points to the authority Jesus Christ has over the spiritual world. If these were "ordinary" visitors from other planets, it is difficult to see why they would be affected by our religious figures.

At the same time, the verses above do not say that if any unbeliever calls out to Jesus with a sincere heart, He will not help them. On the contrary, there are countless testimonies — even outside the UFO field — that Jesus does not despise those who sincerely cry out to Him.

This is perhaps the most common intuitive counterargument.

The answer has three basic levels: 
A) Physical "craft" are, of course, not necessary for demons. They are necessary for human beings. It is precisely the human being who needs a visible, understandable, and technologically credible image in order to accept such a deception and fit it into their evolutionary and technological ideas about "extraterrestrials."

That is why they may use manifestations adapted to the 21st-century person — a person who thinks predominantly in materialistic, scientific, and technological terms. At the same time, under the influence of an evolutionary worldview, such a person often assumes that extraterrestrial civilizations "must exist somewhere." Such an image then gains considerable credibility in the eyes of today's civilization, especially since people have largely ceased to believe in God — measured by the standard of true biblical Christianity.

This principle is not new. Demonic activity throughout history has adapted itself to the imagination and the religious or cultural framework of a given period. In antiquity, spiritual anomalies could be interpreted as gods, spirits, fairies, divine signs, angels, or other supernatural beings. Today, they are interpreted as extraterrestrials.

B) A large part of UFO/UAP observation involves so-called luminous spheres — orbs. For this reason, many researchers, based on the properties of these "objects," also consider the possibility of their immaterial nature. At the outset, then, it is necessary to emphasize that not everything we regard as part of the UFO phenomenon consists of physical "flying saucers." What we probably have here is a mixture of immaterial and material observations and experiences. 

C) Another level of the answer also takes into account certain limitations that these spiritual beings have. If demons want to interact physically with human beings — abduct them somewhere, carry out various parts of their agenda upon them, and so on — they need some kind of physical framework for this. For this reason, it is possible that, in addition to UFO craft, they may also have, for example, secret physical bases.

This physical framework serves primarily for abductions and for a possible hybridization program. In addition, they also need, among other things, physical tools that allow real operations — the extraction of ova, implants, hybridization, and so forth — which purely immaterial demons are probably unable to do, or at least not as effectively.

Such a deception may have various goals — from the "ordinary" diversion of attention away from God to the possibility that it is one of the significant elements of the great deception of the last days, which the Bible speaks about, for example, in 2 Thessalonians 2:9–11:

"The coming of the lawless one is by the activity of Satan rwith all power and false signs and wonders, 10 and with all wicked deception for sthose who are perishing, because they refused to love the truth and so be saved. 11 Therefore tGod sends them a strong delusion, so that they may believe uwhat is false..."

At a time when people reject God and at the same time seek extraterrestrial salvation, higher knowledge, or spiritual enlightenment, the idea of a "cosmic brotherhood" in metal craft is more acceptable to many than the open manifestation of a spiritual being, which could easily be recognized as demonic. This is precisely where the power of the deception lies: it uses human pride, curiosity, and the desire for a different "savior" than Jesus Christ.

This answers the question of MOTIVE: why spiritual beings would use physical objects or physical manifestations at all. In the next section, therefore, we will look more deeply at the very principle of these physical manifestations.

If a phenomenon leaves a radar trace, an imprint in the soil, biological effects, or other measurable manifestations, it may seem that it cannot have a spiritual origin. But that is a hasty conclusion based on ignorance of the true nature of the spiritual world. It is necessary to distinguish between the physical effect and the origin of the phenomenon: the fact that something manifests in the material world does not yet mean that it also originates from the material world.

It is also necessary to take ordinary explanations into account: misidentification of an object, sensor error, satellite glint, a balloon, a drone, an aircraft, a secret military test, an atmospheric phenomenon, or some other natural or technological source. Yet even a genuine physical manifestation of a real UFO does not automatically mean an interplanetary biological civilization.

In brief, then, it may be:

A) A temporary physical manifestation and action upon the real world

In Christian metaphysics, spiritual beings are not "unreal." They are not material in the same way as human beings, but they can act upon perception, the body, and the environment — and, not least, can themselves materialize. Some of the so-called "craft," therefore, do not have to be actual means of transportation, but may be a temporary materialization, projection, manipulation of matter, or some other targeted manifestation whose purpose is not travel, but the credibility of the deception.

The Bible repeatedly shows that spiritual beings can intervene in the physical world: angels ate with Abraham, demons possessed a herd of pigs, the Egyptian magicians in Exodus turned matter into a living creature, and the false prophet in Revelation 13 performs many signs. UFO phenomena involving solid objects, radar signals, traces on the ground, or effects on the body therefore do not have to be merely a "spiritual hallucination," but may be part of a manifestation intended to appear technological, material, and extraterrestrial.

Moreover, many testimonies describe objects that appear physical, but at the same time behave in ways that contradict ordinary physics: sudden changes in speed, instantaneous stops, disappearance or dematerialization, silent hovering, or movement without any visible propulsion. This need not weaken the spiritual interpretation; on the contrary, it may indicate that this is not ordinary technology.

B) Real physical objects and infrastructure

This does not mean, however, that all craft, objects, and so on are merely temporary materializations. That would be short-sighted and would deny many testimonies from countless witnesses: real machines, real wreckage of crashed craft, real reverse engineering, real bodies of dead "extraterrestrials," and so on. It is therefore entirely possible that demons also use actual physical technology, tools, and infrastructure.

Some researchers in this field — for example, L. A. Marzulli — speak in this context of "Fallen Angel Technology," that is, the technology of fallen angels: the physical infrastructure of super-intelligent beings who possess knowledge of physics and natural laws beyond human understanding. They may therefore have tools and technology that appear to us as if taken from science-fiction films.

There is relatively wide room for speculation here, allowing for various theories. My view is as follows: since demons have worked closely with human beings for centuries — and since, in fact, it is, among other things, human free will that gives them the right to act on Earth — the answer may very well be that everything physical is produced by human beings. Human beings are in close interaction with spiritual beings who pass on knowledge and methods for creating advanced technologies.

Materialized demonic beings may also take a direct part in the production, manipulating physical tools and raw materials. Alternatively, it may be a combination of their supernatural activity and "traditional" human production in a highly classified setting. Either way, the range of possible answers to this question is relatively broad. We do not have a final answer to it, but we can put forward hypotheses about the way these beings carry out their agenda.

It therefore appears that, as a civilization, we are exposed to the effects of these influences — real physical objects and physical materializations. When you add to this various natural causes or fraudulent photo and video manipulations, you probably get a realistic picture of what we observe and investigate in the context of UFOs/UAPs.

Physical traces, then, are not in themselves proof of extraterrestrial origin. The decisive issue is not only whether something has manifested physically, but what the origin, purpose, and spiritual fruit of the phenomenon are.

This objection seems strong because it does not concern only lights in the sky, but alleged beings, their bodies, materials, or parts of "craft." Yet even such testimonies do not, in themselves, prove an extraterrestrial biological origin. As we said in the previous answer, angels - demons - can act upon the senses, the body, and the environment, and may manifest in a way that a person perceives as physical.

The so-called "beings" may therefore be either:

1) an illusory effect upon our perception - a spiritual hallucination

2) a temporary physical materialization

3) or a proxy form - a kind of avatar or hybrid bio-technological shell. Such a form would not have to be an independent organism from another planet, but only a carrier, a biological shell, or a means through which a spiritual intelligence manifests itself in the material world. This theory of a hybrid "avatar" is relatively common in ufology, especially in connection with the so-called Greys. It is confirmed, among other things, by the testimonies of abductees who saw many of these beings in incubation tanks right next to other hybrids who resembled humans to a greater or lesser degree.

David Grusch also claimed under oath before the U.S. Congress that the U.S. government possesses "non-human biological samples," which would imply a permanent form of biological body and would probably refer to these avatars.

Similarly, alleged parts of craft do not necessarily prove the existence of real interstellar technology either — see the answer to the previous question. They may be part of the same deception: temporarily created, modified, or deliberately left behind manifestations or technologies intended to give the whole phenomenon the appearance of physical credibility. The goal, then, would not be technical travel, but persuasiveness, or possibly a tool for carrying out a demonic agenda, such as abductions.

Moreover, many of the described "craft" do not behave like ordinary machines, but rather like living or consciously directed entities: they change shape, disappear, react to observers, and violate ordinary ideas of mechanical movement. This may support, rather than refute, a spiritual interpretation of the whole phenomenon. It may be — perhaps in the case of the already mentioned luminous orbs — not a physical vessel, but the physical manifestation of a spiritual being appearing in this way.

This objection is valid if someone claims: "Unexplained = demonic." That is, of course, nonsense. The proper approach in evaluating these phenomena is first to rule out all ordinary explanations: psychological states, natural phenomena, mistaken observations, or even actual extraterrestrial life, and so on. Only then can such cases be evaluated spiritually - especially if they contain elements of intelligence, deception, occultism, a religious dimension, or traumatic content.

So this is not a "demons-of-the-gaps" argument, but a matter of discerning the phenomenon as a whole and evaluating its fruit.

The extraterrestrial hypothesis itself runs into serious physical problems: extreme interstellar distances, the timing coincidence involved in the development of such a civilization - that is, the probability that an advanced civilization would develop within the same time window - the energy requirements, and the behavior of objects that often appear to defy known physical laws. If we add to this the spiritual, occult, and anti-Christian elements, it is legitimate to ask whether this is not more likely a spiritual deception than a biological civilization from another planet.

Regarding the objection of extreme distances and energy requirements, we can, of course, speculate about far more advanced sci-fi technology that could help overcome interstellar distances — as we know from various science-fiction films and series. Even so, many highly suspicious elements still remain, which give us grounds to assume a demonic character.

The related objection of cultural projection may also be partly valid: everyone interprets the unknown through their own framework of knowledge and culture. But the same applies to the secular interpretation as well, which works with its own mythology of evolution, super-civilizations, galactic federations, higher consciousness, or extraterrestrial salvation.

A Christian, then, is not claiming: "We do not know, therefore demons." Rather, the claim is that recurring features such as deception, terror, abuse, occult content, hostility toward Christ, the motif of hybridization reminiscent of Genesis 6, and testimonies about abductions stopping in the name of Jesus Christ fit the biblical framework of spiritual warfare better than the technological mythology of the modern age.

That is true. The Bible does not explicitly address biological life on other planets. God is the sovereign Creator, and He can create one civilization just as He can create thousands. The decisive issue, therefore, is not secular probability based on our estimates of the number of planets, galaxies, or "habitable zones." If God exists, life does not arise by statistical necessity, but by His decision. It is therefore not necessary to turn this question into a firm dogma.

From the biblical context, however, it seems more likely that humanity and the Earth have a unique place in the history of creation, the fall, redemption, and the incarnation of Christ. This, of course, does not mean that a Christian cannot be mistaken on this question, or that they must claim with absolute certainty: "No other biological life exists anywhere in the universe." Rather, it means that the Bible gives us no reason to expect other fallen or redeemed civilizations outside our planet.

But it is necessary to separate two different questions: hypothetical extraterrestrial life created by God, and the present UFO/contact phenomenon. Even if we theoretically allowed for the existence of life beyond Earth, it does not follow that the beings behind abductions, channeling, occult messages, false spiritual "evolution," and so on are genuine extraterrestrials.

So the question is not only: "Could God have created other beings?" — Yes, He could. The question is: "What fruit does this particular phenomenon, which we observe on Earth, bear?" If these were beings created by God and coming in truth, we would expect reverence for the Creator, not the denial of Christ's divinity, the distortion of the gospel, spiritual manipulation, fear, and the terrorizing of human beings.

That is precisely why it is possible to allow for the hypothetical possibility of extraterrestrial life, and yet interpret specific UFO/contact phenomena as demonic deception.

The proper Christian position 

If you are a Christian, you may have relative freedom on this question, but you must always take the following dimension into account:

From a Christian perspective, the first question you should ask a hypothetical extraterrestrial is this: "Who is Jesus Christ?" You can bet your boots that if this question arises in the future, the answers will be something along the lines of: "a higher being," "an extraterrestrial who brought wisdom to humanity," "you are gods yourselves," and so on. In short, they will deny the deity of Jesus, the necessity of His sacrifice, and the issue of salvation; they will relativize the message of the Bible, and so forth.

The hypothetical biblical test for such an encounter, then, will not be technological advancement, but the truth about Jesus Christ. Even if a being came from heaven, even if it performed signs, even if it spoke the language of peace, unity, the evolution of consciousness, and saving the planet, the question remains the same: Does it confess Jesus Christ as the incarnate Son of God, the crucified and risen Lord? Or does it reduce Him to a teacher, an avatar, a genetic project, an extraterrestrial envoy, or one link in cosmic evolution? A Christian does not have to prove every incident. They do not have to know exactly what every object on radar is. Their main task is to discern the spirit of the message.

Remember — the UFO phenomenon does not have to destroy Christianity with any concrete evidence. It is enough if it offers people a new myth of origin, a new myth of salvation, and a new "messiah" without the cross.

This objection is relatively strong and, in some cases, probably justified. A number of abduction experiences may be explained by psychological and neurological processes: sleep paralysis, trauma, suggestion, false memories, or the problematic use of hypnosis.

For example, a person may wake up in a state in which they are conscious, but the body remains temporarily paralyzed. This state is often accompanied by intense fear, a sense of another presence, and vivid hallucinations.

The Christian response, therefore, is not that every claim of abduction is true and demonic. That would be hasty and pastorally insensitive. Many cases may be a mixture of psychological suffering, misinterpretation of an experience, media suggestion, or memories formed later. We must be especially cautious with experiences "recovered" under hypnosis, because this is precisely where the risk of suggestion can be very high. Moreover, as a Christian, I cannot recommend hypnosis; in itself, it represents a spiritual danger.

At the same time, however, a psychological explanation does not necessarily cover all testimonies and cases. It has more difficulty explaining situations involving multiple witnesses, physical traces, missing time, radar data, or recurring spiritual patterns. A particular question also remains regarding the claim of some witnesses that the experience stopped in the name of Jesus Christ. Sleep paralysis may explain the mechanism of fear and perception, but by itself it does not explain the possible spiritual content, the recurring hostility toward Christ, or the effectiveness of Christ's name.

At the same time, sleep paralysis itself is problematic from a spiritual point of view. Although it is a relatively well-described neurological condition, it is still true here as well that it can be interrupted by prayer to Jesus Christ and that it displays suspicious spiritual elements. This weakened state may therefore be exploited by demons, or even induced by them.

A reasonable conclusion, then, is this: psychological factors may explain part of abduction experiences, and they must be taken seriously. In some cases, however, they may be only the "carrier" of a deeper spiritual experience, not its complete explanation. A Christian interpretation therefore does not have to reject psychology. It merely maintains that a psychological mechanism and spiritual activity do not necessarily exclude one another.

Yes, this is testimonial evidence, not a laboratory experiment. These accounts are collected, for example, by American groups such as CE4 Research Group / Alien Resistance. So this is not a standardized scientific study, but neither are these statements worthless. For Christians, however, this argument should be absolutely crucial.

Individual testimonies by themselves do not have the force of laboratory proof. But if a similar pattern repeats itself in countless cases around the world, it becomes a significant indicator. If the phenomenon repeatedly responds specifically to the authority of Jesus Christ, while purely psychological, technical, or extraterrestrial explanations do not satisfactorily account for this fact, then it is legitimate to take it seriously even if you are not a Christian.

In addition, there is also the argument from repeatability — that is, repeated occurrence. CE4 claims that when this response was shared with other abductees, they too were able to bring their experiences to a stop on the basis of the authority of Jesus Christ.

The apologetic point, then, is not: "We have laboratory proof that these are demons." Rather, it is: "We have a recurring testimonial pattern that fits well within the biblical framework of spiritual authority." That is why this phenomenon needs to be tested not only technologically or psychologically, but also spiritually.

If you yourself suspect, or know, that you are a victim of UFO abductions, I urge you: try Jesus Christ. Not as some kind of magical incantation... turn to Him with all your heart and cry out for help. Then you can observe for yourself what happens...

The supernatural in itself does not lead a person to Jesus Christ. It depends on what kind of supernatural phenomenon is being presented to a person and where it leads them. False spiritual manifestations can lead people away from God just as effectively as materialism — only in a different direction.

Demons seek above all to prevent people from believing in the true God, repenting, and submitting to Jesus Christ. The point is to offer a false spirituality: New Age, channeling, false religions, gnosticism, reincarnation, universalism, contact with "higher beings," the relativization of sin, and the idea that salvation does not come through the cross, but, for example, through the evolutionary ascent of consciousness, and so on.

Therefore, the decisive question is not: "Is it supernatural?" The decisive question is: "What fruit does this phenomenon bear?" UFO-related messages often combine technology, esotericism, cosmic saviors, and apocalyptic expectations. They do not offer Jesus Christ crucified and risen, but "enlightenment" without repentance, salvation without the cross, and higher beings in place of the one Lord.

Positive language alone is not enough. In Christian discernment, the decisive issue is not whether a message speaks about peace, love, unity, or protecting the planet, but what relationship it has to Jesus Christ, sin, repentance, salvation, and the truth of the gospel. Even false religious systems often do not come as obvious evil, but as "light," higher knowledge, the unification of humanity, or spiritual wisdom.

That is precisely why rhetoric about peace or ecology can be part of the deception. If such a message relativizes sin, denies the divinity of Jesus Christ, calls His unique position as Savior into question, promotes occult practices, or replaces the gospel with a "cosmic evolution of consciousness," then it is not a neutral good. Love separated from Truth is false and can become a trap.

The Bible explicitly warns that "And no wonder, for even Satan disguises himself as an angel of light. " (2 Corinthians 11:14). Therefore, the question is not only whether the message sounds kind, but whether it leads to the true God, to repentance, and to Jesus Christ — or to a false spirituality in which "higher beings" replace Jesus Christ and salvation comes without His sacrifice on the cross.

I understand that some esoterically inclined friends want to see extraterrestrials as positive beings who want to help us - as these beings themselves often tell them through channeling. In fact, I would wish the same myself... but the reality and fruit of this phenomenon do not allow me to draw those conclusions.

These people have been deceived and, from my perspective, they completely ignore the extremely strong and numerous testimonies connected with the abduction phenomenon. In their attempts to explain it, they dismiss the experiences of hundreds of thousands of victims by claiming that it is merely fear of the unknown, that it is not really true and is only disinformation, or that these are staged attacks by human groups who are merely slandering the poor extraterrestrials... From my perspective, this is a disrespectful and completely naive denial of reality, one that may be motivated by good intentions, but is ultimately very dangerous.

These people who promote the benevolent character of UFOs often have occult "positive" experiences when connecting with these "beings." I therefore understand that, for them, this experience is very powerful and personal, and that it is then difficult to assess it with detachment. However, these ecstatic states and positive spiritual experiences are well known in occultism and false religions, and Christians identify them as demonic even outside the UFO context.

It should not. A Christian interpretation must not replace ordinary secular and military investigation. It is necessary to distinguish between different layers of the phenomenon: flight safety, drones operated by foreign powers, spy balloons, sensor errors, experimental technologies, or military tests. All of this falls within the competence of the state, the military, and intelligence services.

Spiritual analysis concerns primarily the level of contact experiences, abductions, channeling, occult messages, and the religious interpretation of the UFO phenomenon. For example, the American agency AARO - the official Pentagon office responsible for investigating and analyzing unidentified flying objects - rightly understands the UFO/UAP phenomenon as a security issue. Christian apologetics asks about the spiritual background and meaning where the phenomenon goes beyond the ordinary technical level.

So this is not a choice between A or B. Some cases may be a military, technological, or intelligence matter, while other cases may carry a spiritual and deceptive dimension. A responsible approach should take both seriously — the security risks and the spiritual fruit of the phenomena in question.

This objection is valid when directed against irresponsible apologetics. A witness must not be stigmatized, ridiculed, or automatically told that they are demon-possessed. The Christian response should be sober and pastorally sensitive, and it does not rule out professional care.

The claim that a certain phenomenon may be demonic in nature does not mean that every witness "has demons," or that their problem is exclusively spiritual. A person may be confused, frightened, traumatized, psychologically vulnerable, or influenced by suggestion — and therefore they need compassion, not a label.

At the same time, however, it is not possible to exclude the spiritual dimension simply because there is also a psychological dimension, or because someone does not believe that the spiritual dimension exists at all...

The Christian approach, in particular, should offer hope, not fear. The goal is not fascination with the UFO phenomenon or a hunt for demons, but directing a person toward Jesus Christ, toward truth and peace. If the phenomenon has a spiritual dimension, the answer is not panic or condemnation of the witness, but the authority of Jesus, sober prayer, and practical help.

If they are in fact victims of these abductions, Jesus Christ is the only known and effective defense.

This objection is partly correct if someone presents the demonic hypothesis as an ordinary scientific hypothesis in the sense of laboratory physics. "Demonic" is not a physical category for classifying an object on radar, but a theological discernment of the nature of the intelligence, its message, and the spiritual background.

A Christian apologist should therefore not present it as a replacement for technical investigation, but as spiritual discernment. The two can coexist.

This does not mean, however, that the demonic hypothesis is completely untestable. Its recurring patterns can be examined. For example, whether the phenomenon is connected with occultism, channeling, deceptive messages, terror and trauma, hostility toward Jesus Christ, the relativization of sin, and the denial of the gospel. It is also possible to observe whether these phenomena recede after turning to Jesus, renouncing occult practices, and praying in the name of Jesus. If such a pattern repeats itself, it is not laboratory proof, but it is a relevant spiritual and pastoral indication.

The biblical test, then, is not about measuring a demon in a laboratory. It is rather about the question: "What spirit does this phenomenon carry?" This is precisely why the Bible says: "Beloved, do not believe every spirit, but utest the spirits to see whether they are from God ..." (1 John 4:1).

If a given phenomenon does not confess Jesus Christ, leads people away from the gospel, and leads to occult deception, then within the biblical framework it is legitimate to evaluate it as demonic — not on the basis of a gap in knowledge, but according to its spiritual fruit.

In UFO debates, people often do not deal merely with the idea of a single extraterrestrial civilization. On the contrary, an entire catalog of alleged "races" appears in these discussions: Greys, reptilians, Nordics, and other types of beings. But this has a serious logical consequence. If these stories were true, it would mean that we are being regularly visited by several different advanced civilizations at once, each of which independently mastered interstellar travel.

And this is where the problem begins. The more such "races" are supposed to exist, the less convincing it becomes that all of them use similarly material machines, fly through the atmosphere in ways visible to human beings, remain only partially hidden, leave behind unclear evidence, and occasionally crash. Instead of strengthening the extraterrestrial hypothesis, the multiplication of alleged species actually weakens it: it multiplies the number of civilizations, technologies, and visits for which we would expect much clearer evidence.

That is why many secular scientists and skeptics present the following arguments as reasons why they regard the real existence of UFO phenomena as impossible or highly improbable.

1) Interstellar travel is extremely demanding according to known physics 

The nearest star system, Alpha Centauri, is about 4.37 light-years away. That does not sound like a large number, but in reality it represents roughly 41 trillion kilometers. The Voyager 1 probe, one of the fastest objects ever sent out by humanity, would take tens of thousands of years to cover such a distance. Even if some civilization were able to travel at 1% of the speed of light, the journey to the nearest stars would take hundreds of years; at 10% of the speed of light, it would still take decades — and that is only to our nearest neighbors.

For a biological crew, this would mean enormous problems: radiation, energy, fuel, life support, repairs, psychology, microgravity, and maintaining a closed ecosystem. It is not absolutely impossible — if we allowed for the potential existence of sci-fi technologies of the kind we see in various films — but it is so demanding that it seriously undermines the credibility of the extraterrestrial hypothesis itself.

2) Even the timing overlap of civilizations is improbable

For extraterrestrials to be visiting us at present, several things would have to be true at the same time: they would have to exist in the same time window as we do, be technologically far more advanced, be located relatively nearby or capable of extreme forms of travel, know about us, have a reason to come here, and at the same time manifest themselves in an unclear and chaotic way. That is a long chain of assumptions. This remains true even in the case of the objection raised by supporters of the extraterrestrial hypothesis — namely, that humanity is the genetic creation of one of these races, and that they therefore already knew about us.

According to the secular view, the universe is supposed to have existed for billions of years, and the Earth for billions of years as well, but humanity has been technologically detectable for only an extremely short time — roughly the last several decades or centuries. If civilizations arise, develop, and disappear in different periods of cosmic history, then it is in itself highly improbable that we would overlap in time with another advanced civilization precisely now.

3) Multiple extraterrestrial "races" increase the problem rather than solving it

If several different civilizations were visiting us, it would mean that interstellar travel is relatively common. In that case, however, we would expect clearer, more repeatable, and publicly verifiable evidence. Instead, we have chaotic videos, testimonies, incomplete data, and stories that often resemble the pop culture of their time.

4) An advanced civilization would probably have surpassed biological limitations

A civilization capable of traveling between the stars would most likely have long since overcome the limits of the fragile biological body. It could use artificial intelligence, digital consciousness, robotic probes, or other forms of existence. The image of human-like beings sitting in a metal machine and risking a crash looks more like human projection than the probable outcome of technology millions of years more advanced than ours.

5) The crash of "supertechnology"

This is one of the most serious objections to the theory of advanced civilizations. Even if we allowed for technologies that we cannot understand today — for example, the bending of spacetime, wormholes, or other sci-fi concepts — the question still remains: why would such technology fail in such a banal way? A civilization capable of overcoming interstellar distances would probably be able to handle atmospheric flight, our weather, navigation, secrecy, and mechanical reliability without breaking a sweat.

It is fair to add that our reasoning is based on current knowledge of physics. If technologies exist that we cannot yet even imagine, some physical objections to interstellar travel could weaken or disappear. But that does not solve the main problem: why would beings or systems with technology this advanced manifest themselves in such a chaotic, unclear, and above all unreliable way?

In the context of these objections, the interdimensional — or demonic — hypothesis makes much greater sense and, in my view, gives a more satisfactory answer to the entire UFO mystery.
