To believe in a god, you have to suspend reason, not use reasoning. It's fine discussing the possibilities - a god creating everything out of nothing is one possibility - but you have absolutely no reason to believe that a god exists. If I ask you a question that you can't answer, you'd be better off saying "I don't know" as your answer. With religious folks, they use the word "god" to answer questions, and rather arrogantly, they're not saying "god is a possibility". They are saying "god is a fact" without a single atom of evidence. I think you should go back and read my definition of what true open-mindedness is, because the only people "blindly following an idea" are theists, not atheists.
