The Mesopotamians were the first civilization, so therefore, they "came up" with the first religion. The Mesopotamians were polytheistic, which means they worshipped many gods. The gods the Mesopotamians worshipped were based on the natural happenings, their harvest's, hurricanes, and they loved (especially) one god that they claimed "made" the Tigris and Euphrates rivers flood in the summertime every year, so the crops were extra rich from the silt in the water, which came from the mountains.
