Q: If God made the universe then who made God?
A: A typical question asked in Philosophy 101. Now this question would make sense if God was part of time and space—but the Bible clearly teaches that God does not live in our universe physically nor is he limited by time—he is infinite and eternal.
A universe with a beginning does not necessarily demand a creator that also had a beginning. So the question is actually moot.
The God of the Bible is the unmade Cause of the Universe.
