The big bang theory if just that, a theory. The only reason anybody on earth can say there "is no god" is because they don't physically see him. Clearly the Bible says he went into hiding, there would be no more "miracles" he was hiding his presence. It also says if you seek him he will help you and reveal himself to you and that a day will come when he will suddenly appear. I am convinced he is real because I sought him, and he has kept his promises just as the bible says, he always looks out for me. It does seem unreal that a God is just going to pop up one day, but science has no better explanation.
