“God created the universe.” “Okay, then who created God?” It’s a reasonable question, especially if someone has just told you that everything needs a creator. If everything needs a creator, God would need one too, and whoever created God would need another one. We could keep going indefinitely without ever explaining why anything exists. Christians sometimes invite this objection by stating their argument carelessly, so we shouldn’t blame someone for noticing the problem.

The Christian answer is that nobody created God. He has always existed and doesn’t depend upon anything else for His existence. That answer needs some explanation, though, because simply announcing that God is exempt from the rules can sound like we’re changing the rules to protect our conclusion. We need to distinguish between something that comes into existence and something that never began to exist.

Does Everything Need a Creator?

Christianity doesn’t teach that absolutely everything needs to be created. It teaches that God created everything that belongs to creation, while God Himself is uncreated. One familiar argument for God’s existence begins with the claim that whatever begins to exist has a cause. That’s different from saying that everything, without exception, has a cause. If God never began to exist, that argument doesn’t require a cause for Him. Whether such a God actually exists is a further question, but the argument hasn’t contradicted itself.

Other arguments focus on dependence rather than beginnings. You and I depend upon conditions we didn’t establish, including the existence of matter, a habitable world, and the people who brought us into it. Things like us are called contingent because we don’t have to exist, and our existence depends upon something beyond ourselves. The argument from contingency asks whether dependent reality ultimately requires a foundation that doesn’t depend upon anything else. Christians identify that independent foundation as God.

These arguments are related, but they aren’t interchangeable. Something could have existed forever and still depend upon something else for its existence. Having no beginning would tell us how long it has existed; it wouldn’t necessarily tell us why it exists or what sustains it. When Christians describe God as eternal and self-existent, they’re making both claims: He never began to exist, and His existence isn’t borrowed from another source.

Did God Create Himself?

Sometimes people try to explain this by saying that God created Himself. That would make the problem worse, because He would have to exist already in order to do the creating. Something can’t bring itself into existence while it doesn’t exist. The Christian claim is that God was never brought into existence at all.

Psalm 90:2 says, “from everlasting to everlasting, thou art God.” Genesis begins with God already present as the Creator rather than introducing a story about His birth or development. In Acts 17:24–25, Paul describes God as the Maker of the world who gives life to others and doesn’t depend upon human beings to meet His needs. These passages present a God whose existence and life don’t come from creation.

The theological term for this is aseity, which refers to God’s self-existence. You don’t need to remember the word to understand the idea. God doesn’t receive His existence from someone else, require fuel to keep functioning, or rely upon a universe that supports Him. Creation depends upon Him, and He doesn’t depend upon creation.

Is That Special Pleading?

A skeptic might reasonably object that we’ve given God a convenient exemption. If we insisted that everything must have a cause and then exempted God merely because He’s God, that criticism would be justified. But an argument about things that begin to exist doesn’t claim that a beginningless being needs a cause. Likewise, an argument about dependent things doesn’t claim that an independent being needs something else to sustain it. The distinction belongs to the argument from the beginning.

That doesn’t mean we can establish God’s existence just by defining Him as uncreated. We can define an imaginary being however we like without making it real. Christians still need reasons for believing that an eternal, independent Creator exists and that this explanation is better than the alternatives. Answering “Who created God?” removes one objection; it doesn’t complete the entire case for Christianity.

There are serious philosophical disagreements about whether these arguments succeed. Someone might question whether everything that begins to exist requires a cause, whether all contingent reality needs an explanation, or whether the proposed foundation must be personal. Those objections deserve consideration. We haven’t won the discussion merely because we’ve clarified our wording, but we have identified what the actual disagreement is.

Why Couldn’t the Universe Have Always Existed?

If Christians can believe that God has always existed, why couldn’t someone believe that the universe has always existed? That’s a fair challenge, and saying “because the Bible says otherwise” won’t settle it for someone who doesn’t already accept the Bible. We need to examine the reasons for believing that physical reality has a beginning or that it depends upon something beyond itself. We shouldn’t treat the universe’s dependence as obvious while treating God’s independence as something that needs no explanation.

An eternal universe would challenge an argument that depends upon the universe having a beginning. It wouldn’t automatically answer an argument about dependence, because existing forever and existing independently are different claims. Someone could propose that physical reality itself is necessary and requires no explanation beyond its own nature. A Christian could respond by arguing that physical reality doesn’t have the characteristics of an independent, necessary foundation. That’s where the discussion needs to go, rather than simply trading assertions about what has always existed.

We should also be careful about how much any one argument establishes. Even if we conclude that reality requires an uncreated foundation, we haven’t yet established the Trinity, the incarnation, or the resurrection of Jesus. Those beliefs require further reasons and evidence. Arguments about creation can contribute to belief in God without doing all the work involved in defending the Christian faith.

How Can We Understand Someone Who Never Began?

Everything about our experience encourages us to look for beginnings. We were born, the people around us were born, and the things we use were made from something that already existed. It’s difficult to imagine an existence without an origin because we have no personal experience of one. But difficulty imagining something doesn’t establish that it’s impossible. Our ability to form a mental picture isn’t the final test of what can be real.

Christians differ over exactly how God’s eternity relates to time. Some understand Him as existing beyond time, while others understand His eternal life in terms that include succession. We don’t have to resolve that discussion to answer the question at hand. Both approaches can affirm that God never began to exist and was never created by another being.

“Who created God?” is worth asking, and a believer shouldn’t dismiss someone for asking it. The answer is that Christianity understands God as the eternal source of existence, with no creator and no dependence upon anything else. The next question is whether we have good reasons to believe in such a God. That takes us beyond asking who made Him and into examining why anything exists at all.
