Can we imagine that a good and loving God would allow the presence, in a world degraded due to human sin, of other rational beings who would have suffered, although innocent, its consequences?
Formulated around 1950, the paradox bearing the name of Enrico Fermi was sparked by a rhetorical question: why haven’t we encountered intelligent life in the universe? I say “rhetorical” because this question assumes that, unquestionably, little green men exist somewhere, lost in the vastness of galactic space. Or, even if this possibility is not necessarily absolutely certain, many still believe that their existence is very likely. Since I don’t want to unnecessarily prolong the wait, I’ll give the answer right now: we haven’t encountered intelligent life in the universe because it doesn’t exist. For those whose ufological expectations probably hinder the instantaneous reception of this simple answer, I’ll rephrase it more extensively but, hopefully, no less clearly: in no corner of our unique and finite universe are there any intelligent beings – apart from the human species.
I’m sure some readers will feel deceived in their expectations. That is the result of the preparation for an “encounter of the third kind” through the myriad sci-fi productions of all kinds: literary, animated, cinematic, television, etc. In recent years, with the famous hearings in the American Congress where certain military officials, former or current, swear that the U.S. government is hiding remnants of aliens and their spaceships from outer space, it is evident that such beliefs have received a stronger boost than ever before. Consequently, it’s no wonder that film and television producers are only exploiting the trend, seeking, as usual, the philosopher’s stone of commercial success.
For those who still wish to know the arguments on which I base such a firm statement, I will summarize what I have already written in other essays.[*] I specify from the outset that the intellectual framework of my assessment is that of the metaphysics and theology of the Judeo-Christian Tradition. Obviously, for someone who does not accept the essential premises of this framework, which is only possible through faith, my answer makes no sense. But for those who, regardless of their beliefs, are willing to read further, here are the arguments.
Based on certain texts of the Bible, representatives of the Judeo-Christian Tradition have drawn the conclusion of the existence, at the beginnings of history, of an original sin committed by the first humans, Adam and Eve. The story recounted in Genesis chapter 2, where the violation of God’s command is discussed through the consumption of the fruit from the “tree of knowledge of good and evil,” is relatively well-known. The consequences of this act of disobedience to the almighty Creator are dramatically suffered by all the descendants of the two. Exiled from the Edenic garden of Paradise, humans have since been subjected to all the terrible evils of this transient life: diseases, aging, and finally death. Although there is much to be said about what happened in Paradise, I will focus only on the point that interests me for the purpose of my argument.
According to a subtle interpretation applied to certain words of Saint Paul (Romans 8:20), as well as to the verses 17 and 18 from chapter 3 of the book of Genesis, the “fall” of the first humans was accompanied by a “fall” of the entire world. Concretely, this interpretation says that a genuine ontological mutation occurred in both humans and the entire creation. This doesn’t imply that the underlying essence (i.e., the “nature”) of both the cosmos and humans has transformed into something else, but rather only its qualities.
If you want a vivid image of this macro-cosmic event, you can think of the process of developing a photograph taken with a classic camera: first, a negative is obtained, in which everything that is bright appears dark and everything that is dark appears bright. Only after the negative is projected onto light-sensitive paper (in which the key element is silver) will the photograph be obtained, reproducing accurately the photographed landscape.
According to this example, what happened to the world is the obtaining of a negative: instead of remaining bright and colorful as in the dawn of history, before the original sin was committed, the world became like its negative. In other words, devoid of the original light of God’s grace, the world plunged into darkness. Of course, it is not a total darkness, but a strictly spiritual one: that is, we lost that light which made possible the “sight” of spiritual beings – God, angels, saints. This explains the most dramatic fact in all the history of religions.
Although there are numerous beliefs that postulate the existence of God, who, being infinite is omnipresent, yet we do not see Him. In short, we are immersed in darkness. If the daylight were not “functional” for a day, we wouldn’t see anything, right? Similarly, that supernatural light, the “glory” of God, is no longer “functional” for us. That is why saints like Augustine and Hildegard of Bingen say that after the original sin, humanity “became blind.” Not because they couldn’t see the physical world, perceptible through the senses, but because they could no longer see the spiritual world, supernatural, perceptible only through the intellect enlightened by supernatural grace.
I return to my main argument. When Adam and Eve sinned, they underwent a true transformation of their nature, which made them mortals from immortals. Not only did they suffer this “mutation,” but, as Saint Macarius the Egyptian says, “creation, which ministered and served Him (i.e., God), was captured with them.” The entire cosmos suffered the consequences of the first humans’ sin. The metaphysical-theological explanations adequate to an event of such proportions I leave for a future book. However, for now, I will only say that in such a “fallen” cosmos, extraterrestrials cannot exist. On the one hand, nothing is said in the sacred texts of the Bible about the existence of other creatures endowed with intellect/reason outside of angels and humans. On the other hand, we cannot imagine that a good and loving God would allow the presence, in a world “degraded” due to human sin, of other rational beings who would have suffered, although innocent, its consequences. Here, briefly, is the theological-metaphysical argument against the existence of extraterrestrials (there is another argument – named by me the “noetic argument”–much more powerful, but it is too subtle to be exposed in a short essay).
Now I will address the issue that has interested me for many years. And, just like in the case of the presumed existence of extraterrestrials, I will introduce it with a question: Why do our contemporaries need the existence of these beings? Let’s reformulate it: What makes the subject of aliens so attractive to millions and millions of people?
As certain specialists in the study of religions draw our attention, there has never been in the entire history of humanity a culture in which the existence of the unseen world and the spiritual beings that populate it was ignored or even denied by such a large number of people. Assyrians, Egyptians, Greeks, Romans, Indians, Chinese, and any other ancient people believed in the existence of those “extraterrestrials” who populated the “otherworld” – God, the gods, angels, demons, ancestral spirits. Moreover, they were convinced that their lives were decisively and inextricably linked to that world. Their beliefs decisively contributed to the organization of both their lives and societies. From the monograph of the French scholar Numa Denis Fustel de Coulanges, The Ancient City (1864), we can learn how deeply and concretely these beliefs influenced the lives of those in pre-Christian Greece and Rome.
Many modern individuals have lost these beliefs. Their lives are completely a-ritual, a-symbolic, a-religious. Often, not even certain individuals, although baptized Christians, believe in the existence of demons or angels. Sometimes even the existence of God is doubted. One thing is certain: the supernatural world experiences an unprecedented “reflux” in modern times. At the same time, we must admit that man cannot live without faith. But if he doesn’t embrace an authentic religion, then he invents one. I am sure that Chesterton would agree with this statement. Some believe in football, others in the band Imagine Dragons, while still others worship the photograph of Elvis Presley. Extraterrestrials can represent exactly this type of reinvention of religion in a secular style. We no longer believe in angels and demons? Then we believe in Luke Skywalker and the good aliens, or we believe in Darth Vader and the evil aliens (just look at what was in Mos Eisley!). Or, who knows? Maybe some prefer even the infamous Joker.
On the other hand, not only “sex sells,” as advertisers – rightfully or wrongfully – say, but also aliens sell. And quite well. It is no coincidence that films and series like Star Wars, Star Trek, Close Encounters of the Third Kind, E.T. the Extra-Terrestrial, Signs, and so on, have had the success we all know. Often of questionable artistic quality, but almost always well-received, they prompt post-modern individuals to pay good money for such moments of escape from everyday banality. Who wouldn’t want to see what hypothetical ETs look like? Before the films, there were science fiction novels and countless comic series with monsters of all kinds. Herbert George Wells described in The War of the Worlds what bellicose Martian invaders look like, and Orson Welles became famous at just 23 years old – in 1938 – after causing panic among listeners by announcing that Martians had invaded Earth. And if we remember Tom Cruise, who probably ran more than 100 miles chased by aliens in the screen adaptation of the same Wells story, it is clear that we are dealing with a marketable subject, which makes more money than participating in marathon trials at the Olympic Games.
I can go on endlessly enumerating the cultural phenomena generated by ETs. And the list of “religions” born from belief in their existence is long. However, I believe that there is a more important direction in which the entire discussion can be oriented. The first step in this regard may be a serious reflection about the meaning and criterion of discerning an authentic religion. Otherwise, one day we may find ourselves with some president proposing a new “cult” whose gods will resemble those thirteen aliens – from Indiana Jones and the Kingdom of the Crystal Skull – whom the Ugha tribes worshipped. Not even the extraterrestrials can imagine what our politicians are capable of when it comes to preserving and increasing power.

“We cannot imagine that a good and loving God” would allow innocent beings to suffer because of human sin, is a standard in theodicy arguments, and is clearly not valid. God allows the suffering of innocents all the time. He has given rational beings the dignity of being true actors, and our actions have real consequences for others as well as ourselves.
I would suggest that the author read the first two books of C.S. Lewis’s Ransom trilogy (Out of the Silent Planet, and Perelandra).
BTW, while I think extraterrestrial life probably exists, I am very skeptical about the actual nature of the UFO phenomenon.
Good article. I also think macroevolutionist also desparately need aliens to exist to show that man is capable of evolving
Logic demands that no other human-like intelligent life forms exist — at our communication level. Forget Bible allegories, fables, or mythological tales scribed by mere mortals that can never be proven true. Astronomical science has established the reproducible fact that countless Earth-equivalent planets abide in our galaxy. And that’s not including the probable trillions of galaxies in our universe that raise the likelihood of other intelligent life forms of our shape and intelligence to nearly 100%. Yes, other life forms of our caliber have exited or still do exist out there in the far beyond.
So, why haven’t we heard anything from alien life forms despite our efforts to do so? It stands to reason that advanced technology eventually induces self -annihilation. The paradox of prosperity.. We’re seeing the first stages of that in our development of the atomic bomb. and nuclear fission. Advances in trans-humanization are threatening us with Ai bots that could decimate our human race, as per the film Terminator. Or experiments in climate control darken our skies forever as per the film Matrix with a nuclear winter in which all life forms die. Or the pesticides we overuse cause a transgender tsunami that will force our reproduction rate to near zero.
So many opportunities by which this human race can abolish itself, because human nature could not change to avoid this One can speculate it’s predestined. And somewhere out there another human race may be on the verge of their own industrial revolution., anxious to hear from other beings. Their advanced instruments will also report only a deathly silence, and they’ll wonder why, until they destroy themselves as we did..
I do admit the existence of extraterrestrials might cause difficulties with regard to the Fall, but arguably paleontology itself could cause some difficulties on that. (Unless you just choose to reject anything other than Young Earth Creationism.)
From a scientific basis I think UFOs are implausible, but some extraterrestrial intelligence is neither proven nor disproven. And to be honest from a scientific view I think disproving it would be difficult because the Universe is vast. If extraterrestrial intelligence is say “one per galaxy” it could mean millions of years for them to give us a message or us to give them one.
So I think for the foreseeable future a position is sort-of a matter of faith in either direction. It is maybe interesting though that on this issue agnosticism about extraterrestrials feels maybe rarer than agnosticism about God. People insist there must be aliens or that there must not be. Lack of evidence either way would seem to make “I don’t know” a fairly standard answer, but I’m not sure I encounter it much.
I do agree though that the faith or confidence there must be aliens does feel like it’s about a need. A belief that the Universe “can’t” be mostly empty of intelligent life or that “their must be something better than us out there.” But the possibility there is nothing else does seem worth contemplating. (I think a Christian can go either way on this. Even the original sin argument might not preclude the possibility of an intelligence arising after us, within the last 5,000 years or so.)
People can “need” to believe in aliens, or to deny any possibility of them. Doesn’t matter either way. It’s just a wish.
If intelligent life exists on other planets, there are a multitude of possible reasons for no contact. Insurmountable distance. Maybe they haven’t developed technologically. Maybe they did and destroyed themselves. Maybe they did, took one look at us, and decided to stay well away from us. They may even have deliberately chosen not to develop too much technology. And so on.
I’m sceptical about UFOs being aliens. If they are, and want to contact us, surely they have learned at least one of our languages by now. If they just want to keep an eye on us, they should be well able to keep our of our sight.
There are other explanations, including the demonic, and some evidence for that.
