The Bible does claim that God had no beginning. Theres no proof of this about having one universe, thats just your view. And if there is forms of energy that have no beginning nor end then God could well exist in a whole different universe which we can't detect. Because if this is the case, its possible for a God who had no beginnng or end, which takes who created God out of the question. I still see it highly unlikely that these forms of matter got there themselves and had no beginning, and created all this today with a big bang, it seems like a big plot. Just say there was a box, empty with nothing in it, the only way to get something inside would be to open the lid, well these forms of energy have no beginning or end in this universe. so it may have been put in from another universe, which is what i believe.
