I almost hate to enter this conversation, but it didn't come from nothing. The current theory is that it was the primordial black hole, that released its energy, to form the current universe.Not necessarily true. There is much that science can't prove either.
On the other hand, scientists and atheists have agreed that the universe came from a "big bang," meaning everything created from nothing.
And that is probably one of the greatest miracles of all time.
So, why not believe in a God that could do that?
