There seems to be a bit of a paradox in this though. It’s wrong to say that the universe could start from absolutely nothing, but didn’t the same happen to God? Essentially he is something (a god), and he obviously came from nothing himself, so we could go straight back and say the universe then could have come from nothing on its own too (because obviously something can come from nothing). One can't be true without the other being true, and an endless cycle suddenly emerges.
I used to worry about that all the time. Who created God?
But that whole question and paradox is based on our subjective view of the universe. IF He just spoke it all into existance, then who are we but mere specks? And maybe we shouldn't even ask that question. It may not be able to be understaood by us anyway.
About the only thing biblically we have to go on, is that we were created in His image.
