....or maybe the stories in the Bible and Quran were made up by humans to rationalize their atrocious actions?
A human who wages war and kills others is evil....unless he claims it's by God's command. Then the same evil actions suddenly seem to become 'righteous' (at least in the eyes of his fellow believers).
Don't freak out....you have your whole life before you to decide whether you believe in any gods or not, and what their qualities are...
