Not necessarily.<quoted text>
So who created God?
If the universe needs a creator then the creator needs a creator.
If the creator doesn't need a creator then why should the universe?
Theists have this weird idea that God doesn't need to be explained. He does.
First Cause is a scientific approach to explain existence of a physical phenomenon - the universe.
If God created science as we know it - it does not follow that He Himself can be explained by it.
