Can atheists give an argument against God?

---This sleaze ball will never approve a comment against his argument...so...

It is perfectly possible to be an Atheist. What was that guy talking about? A Theist is a believer, and Atheist is a non-believer. It's fairly simplistic really. As for the argument against the Christian god, I have none save for the contradictions in the bible. for gods in general, you must remember their origins. The Abrahamic god for instance is one of a number of polytheistic gods. He was considered the greatest of them, so they turned on the others and eventually forgot them.
