I've got to try and answer your question of "how did God survive the big bang".
First of let me start by saying that as an atheist I don't believe that God even exists, let alone was responsible for the creation of the universe.
But putting that aside for a moment, if I were a person of faith and believed that God did create the universe, surly if he were able to do such a thing he would have made provisions to keep himself "safe" in the process, presumably outside of our universe.
That's what I would say, if I believed in it.
