Aliens. Just the word makes some people picture UFOs zipping through the night sky and others roll their eyes at the thought of little green men. But what if we told you this isn’t just a sci-fi thing? What if there’s a chance—however small—that the Bible might actually hint at something extraterrestrial? Yep, we’re going there.

Now, before you start imagining Moses chatting with ET or the Apostle Paul cruising around in a spaceship, let’s set some expectations. The Bible doesn’t flat-out say, “Hey, there are aliens, and they live on Planet X.” But there are a few curious passages that have made Christians—and plenty of skeptics—stop and think, “Hmm…could this be talking about something out there?”

Over the centuries, Christians have grappled with the big questions: Are we alone in the universe? If not, what does that mean for faith, salvation, our place in God’s creation, etc? Some believe these questions stretch Scripture way too far. Others think the Bible leaves the door wide open for the possibility of life beyond Earth.

We'll attempt to give you the closest thing to an answer as possible in this article. We’ll explore the Bible’s mysterious verses, what theologians and Christians have said about aliens over the years, and why this question matters for believers today.

Are Aliens Mentioned in The Bible?

Did you ever read certain parts of the Old Testament and thought, “Wow, this sounds a little… otherworldly,” ? Yep, meet too. While the Bible isn’t a sci-fi novel, some passages have stirred debates about it's talking about. Are those supernatural encounters, angelic beings, or maybe—just maybe—aliens.

The Nephilim: Giants, Angels, or Something Else?

Here’s a bible passage that has sparked endless speculation regarding aliens:

"The sons of God saw that the daughters of humans were beautiful, and they married any of them they chose. Then the Lord said, ‘My Spirit will not contend with humans forever, for they are mortal; their days will be 120 years.’ The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown." — Genesis 6:2-4 (NIV)

Let's back up. What’s going on here? The “sons of God” marrying human women and producing Nephilim—a mysterious group often described as giants—sounds like something out of a fantasy epic. Some scholars interpret the “sons of God” as fallen angels, which fits into a spiritual worldview. But others have wondered: Could this be describing beings not from Earth? Perhaps “sons of God” refers to intelligent life beyond our understanding—angelic, extraterrestrial, or otherwise.

While there’s no definitive answer, this passage leaves the door open for curiosity. At the very least, it shows that the Bible isn’t afraid to acknowledge mysteries that go beyond human experience.

Ezekiel’s Vision: A UFO or God’s Glory?

If you’re looking for the most “sci-fi” moment in the Bible, Ezekiel’s vision in Ezekiel 1 is a strong contender. Let’s set the scene: Ezekiel is standing by the Kebar River when he sees something incredible in the sky.

“I looked, and I saw a windstorm coming out of the north—an immense cloud with flashing lightning and surrounded by brilliant light. The center of the fire looked like glowing metal, and in the fire was what looked like four living creatures.” — Ezekiel 1:4-5 (NIV)

The description gets wilder: each creature has four faces (human, lion, ox, and eagle) and wings that touch each other. Then Ezekiel sees wheels within wheels, sparkling like topaz and moving in ways that defy physics:

“Wherever the spirit would go, they would go, and the wheels would rise along with them; because the spirit of the living creatures was in the wheels.” — Ezekiel 1:20 (NIV)

Some interpret this as a symbolic vision of God’s glory—majestic, awe-inspiring, and beyond human comprehension. But there is a questions that's been left unanswered. Could Ezekiel be describing advanced technology he didn’t have the language to explain? 

The “wheels within wheels” have even been interpreted as a description of something outside of our planet by some enthusiasts. The truth? There is none...for now.

The Morning Stars in Job: Angels or Something More?

In Job 38:4-7, God reminds Job of His unmatched power by asking a series of rhetorical questions about creation:

“Where were you when I laid the earth’s foundation? … while the morning stars sang together and all the angels shouted for joy?” — Job 38:4,7 (NIV)

Most theologians agree this poetic imagery refers to angels rejoicing as God created the world. But could “morning stars” also hint at intelligent life beyond Earth who witnessed creation? The Bible doesn’t say directly, but the passage does remind us that God’s creation is vast, full of things we can’t begin to fathom.

A Universe Beyond Our Imagination

Here’s the thing: the Bible was written to guide us spiritually, not to provide a map of the cosmos. But it does leave room for awe and mystery. Passages like these invite us to consider the possibility that God’s creation extends far beyond what we see here on Earth. As Psalm 19:1 says:

“The heavens declare the glory of God; the skies proclaim the work of his hands.” — Psalm 19:1 (NIV)

Does that “glory” includes aliens or not? We don't know. Howver, the point is clear: God’s universe is vast, beautiful, and filled with wonders we’re only beginning to understand.

In the end, none of these passages offer concrete evidence for extraterrestrial life, but they do remind us that God’s creation is far bigger and more complex than we often realize. So, are aliens in the Bible? That’s for you to ponder, but one thing’s for sure: Scripture never shies away from the mysteries of the universe.

What Do Theologians Say About Aliens?

When most people think of theology, they’re not picturing theologians debating aliens over cups of coffee. But surprisingly, the question of extraterrestrial life isn’t new. For centuries, Christian thinkers have been wondering: If otherworldly beings exist, how would that fit into the grand story of creation, sin, and redemption?

Augustine’s Take: The “Focus on Earth” Club

Let’s start with Augustine, one of Christianity’s heavy hitters from the 4th century. In his classic City of God, Augustine doesn’t directly address aliens (it’s hard to speculate about Mars when you’re in 400 AD), but he does focus heavily on humanity’s unique role in creation. For Augustine, Earth—and specifically, human beings—are the centerpiece of God’s work.

If aliens were out there, Augustine might say they’re not part of the same redemptive story as humanity. After all, the Bible says:

“For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.” — John 3:16 (NIV)

Notice it says “the world,” not “the galaxy.” Augustine would likely argue that Jesus’ incarnation and sacrifice were specifically for us Earthlings, leaving little theological space for extraterrestrial beings.

Thomas Aquinas: If It Exists, God Made It

Fast forward to the 13th century, and you’ve got Thomas Aquinas, another theological powerhouse. Aquinas was all about using reason to understand God’s creation, and his writings leave the door open for the possibility of extraterrestrial life. Why? Because for Aquinas, God’s power is infinite. If God can create Earth, why couldn’t He create other worlds with intelligent life?

Aquinas believed that everything in existence is part of God’s divine plan. So, if aliens exist, they would fit into that plan somehow. In other words, their existence wouldn’t threaten Christian doctrine—it would just expand our understanding of God’s creativity. As Psalm 147:4 reminds us:

“He determines the number of the stars and calls them each by name.”

If God is naming stars, who’s to say He didn’t sprinkle a few civilizations out there too?

Modern Perspectives: To Infinity and Beyond

Today, theologians are split on the alien question. Some argue that the existence of extraterrestrial life wouldn’t change anything about Christian faith. God’s sovereignty, Jesus’ sacrifice, and humanity’s unique relationship with Him would all still stand.

Others see it as a challenge. For example, if aliens exist, do they need salvation? Did Jesus’ death cover them too, or would they need their own Savior? And how would their existence affect humanity’s role as beings made “in the image of God” (Genesis 1:27)?

While there are no concrete answers, the consensus among many theologians is this: If aliens exist, it doesn’t diminish God’s greatness. Instead, it shows that His creation is even more vast and diverse than we imagined.

C.S. Lewis—author of The Chronicles of Narnia and a brilliant Christian thinker—had some fascinating ideas about aliens. In his essay Religion and Rocketry, Lewis speculated that if extraterrestrial beings exist, they might not be fallen like humans are. Maybe they live in perfect harmony with God, untouched by sin.

But if they are fallen, Lewis argued that God could find a way to redeem them too. After all, Jesus’ death and resurrection are central to Christianity, but that doesn’t mean God’s redemptive power is limited to Earth. As Lewis put it, “God’s mercies are wide enough.”

What This Means for Christians and the Faith

The Bible says in Genesis 1:27:

“So God created mankind in his own image, in the image of God he created them; male and female he created them.”

Christians have long debated what being made in God’s image actually means. Is it our ability to reason, to create, to have moral awareness? Or is it something deeper, like our capacity for a relationship with God?

Now, if intelligent life exists, the question becomes: Is it also made in God’s image? If aliens have souls, emotions, and intellect, some theologians argue that they, too, could reflect God’s image in ways unique to their species. Others believe this distinction is reserved for humanity alone. 

For Christians, humanity has always held a unique place in God’s creation. We’re described as caretakers of Earth (Genesis 1:28), and Jesus came to save us. But if aliens exist, does that diminish our significance?

Not necessarily. Think of it this way: God’s love for humanity doesn’t shrink just because He might love other beings, too. It’s like parents loving multiple children—it doesn’t make one child less important. Instead, it expands our understanding of how big and all-encompassing God’s love really is.

At the end of the day, theologians—ancient and modern—agree on one thing: God is bigger than we can comprehend. Whether or not aliens exist, the truths of the Bible remain unchanged. As Deuteronomy 29:29 says:

The secret things belong to the Lord our God, but the things revealed belong to us and to our children forever.

In other words, it’s okay to wonder, to speculate, and to marvel at the universe. But ultimately, some mysteries belong to God. And maybe, just maybe, that’s part of the beauty of faith.

Community Questions Regarding Aliens

1. Are aliens real, yes or no?

The Bible doesn’t give us a definitive yes or no. Science hasn’t confirmed their existence either, so it’s still an open question. Christians generally agree that if aliens exist, they’d still be part of God’s creation, just like everything else in the universe.

2. Are aliens mentioned in the Bible?

Not directly. You won’t find verses saying, “And the aliens landed…” But there are mysterious passages—like Ezekiel’s vision (Ezekiel 1) and the Nephilim in Genesis 6—that some people interpret as potential references to extraterrestrial beings.

3. What does the Bible say about aliens?

The Bible doesn’t explicitly talk about aliens. It focuses on God’s relationship with humanity and His creation on Earth. That said, the Bible emphasizes God’s sovereignty over all things, seen and unseen (Colossians 1:16), which leaves room for the possibility of other creations beyond Earth.

4. Are aliens demons?

Some Christians speculate that UFOs or extraterrestrial encounters could be demonic in nature, given the Bible’s warnings about deceptive spiritual forces (2 Corinthians 11:14). However, there’s no biblical evidence directly linking aliens to demons.

5. Is there any church history regarding aliens?

Yes, but not much. Early church figures like Augustine and Aquinas didn’t discuss aliens specifically, but their writings about the vastness of creation leave room for speculation.

6. Does the Bible say God created aliens?

The Bible doesn’t mention aliens, but it does say that God created “the heavens and the earth” (Genesis 1:1) and that “all things were created by Him and for Him” (Colossians 1:16). If aliens exist, they would be part of God’s creation, just like stars, planets, and humans.

7. Do Christians believe in aliens?

It depends on the Christian. Some are open to the idea of extraterrestrial life, seeing it as a possibility within God’s creation. Others are more skeptical, focusing on the Bible’s silence on the subject. 

8. What does the Bible say about space?

The Bible marvels at the vastness of the heavens, often pointing to the stars and skies as a testament to God’s glory:

“The heavens declare the glory of God; the skies proclaim the work of his hands.” — Psalm 19:1

While it doesn’t give a scientific breakdown of space, it says the universe reflects God’s power and creativity.

9. What does the Bible say about other galaxies? Does the Bible mention other planets?

The Bible doesn’t explicitly mention galaxies or name other planets (besides Earth). However, it does reference the “heavens” in ways that could include the stars, planets, and other cosmic phenomena. Psalm 8:3 says:

“When I consider your heavens, the work of your fingers, the moon and the stars, which you have set in place…”

10. Are aliens fallen angels?

The Bible never equates aliens with fallen angels, and this idea is more of a theory than a scriptural teaching. Fallen angels are described as spiritual beings who rebelled against God, not physical entities from another planet.
