The Sumerians were the first known people to settle in Mesopotamia over 7,000 years ago, between the Tigris and Euphrates rivers (modern day Iraq). Sumer was often called the cradle of civilization. By the 4th millennium BC, it had established an advanced system writing, spectacular arts and architecture, astronomy and mathematics. The origin of the Sumerians remains a mystery till this day.

He is the firstborn of An and Ki and the first of the Anunnaki. Enlil´s city is Nippur, the religious capital of Mesopotamia, and his temple is the E-Kur. His sacred number is 50. He holds the 'tablets of destiny', cuneiform tablets on which he writes the fate of everything on earth.
