Every so often, another headline about aliens or UFO sightings takes over social media. This time, the U.S. government has released official documents affirming the existence of UFOs (unidentified flying objects). People are so fascinated by the idea that maybe, just maybe, other beings exist in the universe that some are wondering, “What does the Bible say about aliens?”
The question has grown even louder as theoretical physicist and professor Michio Kaku says that, at this point, we have to entertain the idea that aliens may exist.
Those who disagree with Kaku say that, even if aliens are real, it’s extremely unlikely that they would find Earth and make the long trip. But Kaku says this objection doesn’t account for the full picture. After all, he reasons, since the universe is billions of years old, alien races may very well have had millions of years to develop the technology they need to reach our planet.
And therein lies the first problem with the idea of aliens, says Answers in Genesis Founder Ken Ham—billions of years.
Aliens and Evolution
It’s extremely rare to find someone who believes in aliens who doesn’t also believe they’ve had millions of years to evolve beyond humans. Kaku’s evolutionary mindset is fairly standard among UFOlogists (those who believe in aliens and study UFO sightings).
“In his worldview, the scientist believes that the universe is billions of years old and evolution is occurring on planets throughout the universe,” says Ham. “So some supposed alien race may have evolved and developed far superior technology than we earthlings have managed to accomplish. But in order for such an idea to even be entertained, you have to accept the notion of a billions-of-years-old universe and biological evolution (contrary to the observational evidence of a young universe from astronomy!).”
Kaku certainly isn’t the only scientist to believe evolution opens the door to aliens. Other leading evolutionists like the late Dr. Carl Sagan have theorized that outer space is home to other intelligent life.
Aliens From a Biblical Worldview
But alien theories simply don’t make sense from a biblical perspective, Ham says. Let’s start with the first chapter of Genesis to understand why. In the biblical Creation account, we see that God created the earth first. On Day Four, He made the sun and moon for the earth, and then He made the stars as well.
Genesis 1 implies that the earth is very special to God and that it takes center stage in His plan for Creation. Several other passages throughout the Old Testament indicate the same:
“The heavens are the Lord’s heavens, but the earth he has given to the children of man” (Psalm 115:16, ESV).
“Heaven is my throne, and the earth is my footstool” (Isaiah 66:1, ESV).
“It is he who sits above the circle of the earth” (Isaiah 40:22, ESV).
These verses seem to imply that God considers the earth special and set apart when compared to the rest of the universe. It also seems to be the only place He created for life. And based on what scientists have discovered of the universe, this appears to be true.
There are certainly other theological problems with the idea that aliens exist. For instance, if there are intelligent beings on other planets, then do they have free will like humans? And if they have free will, have they fallen into sin? And if they’ve fallen into sin, does God have a plan to redeem them?
Do you see how this line of thinking strays further and further from the gospel message—that Jesus, the Son of God Himself, came to earth as a man to fully atone for our sins because this was the only way we could be reconciled to God? As far as we can see in Scripture, Jesus has not done for any other race what He has done for human beings. Remember, He’s the God-Man, not the God-Alien.
Now, this line of reasoning doesn’t apply to extraterrestrial animal or plant life, of course. But so far, scientific evidence for biological life on other planets is extremely slim at best.
So next time you hear someone talking about aliens, try bringing up these passages to segue into sharing the gospel and God’s love!
