Ok, but what evidence (physical or reasoning) do you have to believe that? I mean, I could say that I think there are unicorns in the Rocky Mountains, but people wouldn't (generally) believe me unless I gave them evidence and reasoning.
My views are that the Big Bang was the start of the universe as it is today; it was (or rather is) a rapid expansion of space time. Before that, we cannot say anything due to the nature of the universe (or rather how we understand the nature of the universe).
However just because we cannot explain what happened before the Big Bang (or even if there was a "before" the Big Bang), does not mean that this gives any credibility to the idea that God somehow exists.
