Way back in the times of Mesopotamia , considered the first civilization, religion was created. They had well over 2,000 gods they believed in. Each one of those gods stood for something in nature. If you did something the gods didn't like then you would be punished by the gods.

This was to instill fear so the citizens would not rebel. Over the centuries, more religions came to be. Each ones gods had standards that just so happened to be what the rules wanted. Some rulers even called themselves gods. People who make rules understand how to manipulate religion to give themselves power. That is why I refuse to kneel to some deity who for some reason decides what's right and what's wrong for me.
