Begs the Question there was a 'Whom' but the point is well made. Read Hawkins recently and he said we can't concern ourselves with what happened before the BANG! because there were no rules, no natural laws, no time, no anything before that so it didn't exist! Oh, that explains things.
I like to put thus, "What went Bang!?"
You may assume God exists if you wish but it is all the same. Nobody really knows. That's the one thought nobody wants to accept.
Hawking, bless his heart, is a four year old among two year olds. Despite all his human intellect, he has nary a clue what happened before the "big bang" (assuming there was a "big bang"), and moreover, he is incapable of knowing. None of us are capable of knowing. It must gnaw at him to no end. If Hawking is good, God may tutor him on some truly advanced physics after he's checked out of this life.
