I suspect the origins of some religions went like this:
Judaism:
Unknown priest: "Let's make one of our gods supreme and the only god and then use it as a justification to invade our neighbours!"
Christianity:
Mary: "No, dad, please don't stone me. I'm still a virgin. Ummm... god did it!"
Islam:
Mohammed: "Let's take the Christian god and change its character a little to justify invading and slaughtering our neighbours!"
Hinduism:
Unknown priest: "Let's have millions of gods. That way the people will be too confused to ask questions!"

"You did WHAT? With WHO? WHERE???"
