Gods and Goddesses

I learned that people made sacrifice just to impress the god or goddesses. Like they killed animals for the gods to eat, they killed beautiful women for the god to fall in love with. They would do anything to impress the gods so they could get something in return. So if they do something for the water god in return they get rain. People build ziggurats to reach nearer heavens. The purpose of a ziggurats is for to honor the gods.
