Answer
We know that the events surrounding the end times, as described in the Bible, will include a powerful deception (Matthew 24:24; 2 Thessalonians 2:11). Recently, interest has been rising in the theory that this deception will include alien beings supposedly from another planet. Although the Bible gives us no word about whether or not aliens exist—there is no inclusion of them in the creation account in Genesis, and no mention of them elsewhere—the Bible does tell us about visitors from another world—the spiritual world.
Since the beginning, instances of demons (fallen angels) visiting the earth have been witnessed and recorded. We know from Eve’s encounter with Satan that demons are interested in monitoring (and altering) the progress of humanity. They want to be involved, with the goal of drawing humanity away from the worship of God and turning mankind’s attention instead to them. Another notable instance of their interaction with us is found in Genesis 6:4 with the arrival of the “sons of God.” The Genesis account states that these powerful beings had sexual intercourse with women and produced a super race of beings known as the Nephilim. This sounds like the stuff of science fiction, yet it is right there in the Bible. There are striking similarities between this account and the accounts of other ancient cultures. The writings of the ancient Sumerians, for example (who were the first to produce a written language) mention the presence of the “Anunnaki” who were deities that came from heaven to dwell on earth with men. It is also interesting to note that the Sumerians’ gods often came to them in the form of snakes.
These accounts, seen alongside the amazing things created by ancient man, make it possible to theorize that demons, in the form of beings from another world, came to earth, bringing spectacular wisdom and knowledge to men, and “intermarrying” with their daughters in an attempt to draw men away from God. We already see from Eve’s experience with the serpent that demons will use the temptation of superior wisdom to ensnare man and that man is very susceptible to it.
Could the end times include a similar alien deception? The Bible doesn’t directly address the issue, but it is certainly plausible, for a variety of reasons. First, the Bible tells us that the world will unite under the power of the Antichrist. In order to achieve an agreement between all the world’s religions, it would make sense for the “uniter” to come from an entirely new source—an extraterrestrial source. It is hard to imagine one religion becoming head of all the others, unless new, unearthly knowledge were the source of the appeal and power of the new “religion.” This would be in keeping with past deceptions and would be a very effective way to deceive a large number of people.
Second, this deception could provide an answer to the problem of earth’s origins. The scientific theory that the evolution of life on earth was spontaneously generated still has no answer for life’s beginnings. Many claim that there is evidence for a “big bang,” but there is no explanation for what caused the supposed big bang to occur. If alien beings arrived and gave us an extraterrestrial explanation for life on earth, the origins of the world religions, and even the origins of our planet, it would be very persuasive.
That said, we should not fear. The Lord has said that He will not leave us or forsake us, and that He will protect us (1 Kings 8:57; Matthew 10:31; Isaiah 41:10). Demons / angels are not omnipotent, nor are they omnipresent. Jesus said that in the end times His appearing would be like lightning—easily visible to all. He said to be wary of any being that says “I am the Christ” or any group that says “He’s over there” or “He’s in here” (Matthew 24:23-24). He said that vultures gather around a dead body, meaning that if you see a group of people gathering around someone claiming to be Christ, that person is death and a false prophet.
We should be wary of any person or being that produces signs and wonders without biblical fidelity or the presence of obedience to the Lord Jesus, anyone who provides a way to unite the world religions or governments (Revelation 13:5-8), any being that promotes unnatural sexual relationships (Genesis 6:4; Jude 1:6-7), and of course, any person who denies that Jesus is God (2 John 1:7). Furthermore, anyone who presents a “substitute” Jesus, who represents Him as “a god but not the God” or who claims He was merely a good teacher, simply a human, or even a super-human or an alien creature, is a deceiver.
Lastly, if demons manifesting as aliens are part of the end times, we should remember that they, too, are created beings subject to a sovereign God and ultimately answerable to Him. Whether in alien form or not, the descriptions of demons in Revelation are frightening (Revelation 9:1-12), but we should not fear those who can only kill the body. Instead, we should only fear the One who can kill the body and the soul in hell (Matthew 10:28). No matter what happens to us on the earth, we should trust that the Lord is the Savior, Redeemer, and Protector of the souls of those who put their trust in Him (Psalm 9:10; 22:5).
