Well first off I am going to state that I can't prove to you that there is no god, just like you can't prove to me that there IS a god or that there are magical unicorns on the dark side of the moon. Let me ask you this, if a man walked up to you and said "There is a man in the sky that made you and everything around you, and he gave you freewill but you still have to worship him or you will burn in a lake of fire forever after you die". Would you believe him? Of course you wouldn't. To answer your first question on how the universe was formed, I personally don't give a fuck. Some people want to "uncover the secrets of the universe" and that's all fine and dandy for them but I really don't care unless it directly effects me. Let me answer your last question with a question. How can you believe there IS a god. How can YOU be that foolish. Look at computer in front of you, did god make that? No, a MAN made that. I really don't give a fuck if you believe in a god, that's your own business, but don't sit there and say you can't believe that some people might have a rational thought and think that a magic man in the sky might not exist.
