Basically what you're saying is that since we cannot yet figure out what happened before the big bang, or what caused it, it must have been supernatural. Lightning, earthquakes and magnetism used to all be considered supernatural before we were able to figure out, with logic and science, what they were. Do you honestly not see the pattern?

I agree that the concept of something from nothing may be beyond our comprehension and therefore we simply default to some kind of great creator or life force of it ALL. However you cannot, with rational and logical thinking anyways, say that the god of your bible is it. And no, I will not even begin to discuss why your religion is or isn't the real religion, because that is just irrelevant.
