Introduction for sumer civilization

He Sumerians were the most extraordinary people who ever lived on the face of the earth. They seemed to come from out of nowhere, and they single-handedly invented civilization when most of the rest of the world was still living in the Stone Age. What’s more, they did it thousands of years before anyone else. In regard to the Sumerians, you will need to revise your concept of ancient in comparison to the "ancient" Greeks, Romans, and Egyptians. The Sumerian civilization was already ancient when it ended in 2004 B.C., twenty centuries before Julius Caesar, sixteen centuries before Socrates, and seven centuries before Tutankhamen.

At the dawn of history, the Egyptians were the only people with a civilization comparable to that of the Sumerians (although the Sumerian civilization was much older). There has been some debate on whether they created their civilizations independently or if they cooperated with each other. The historic record seems to indicate that they built their civilizations independently. There is no mention of the Egyptians in the Sumerian archives, or vice-versa, and there is no direct evidence that they had a noticeable influence on one another, except for their propensity to build giant pyramids and ziggurats. Although on a modern map they appear to be quite close, they never had any direct contact with each other. Back then, the world 
was a much larger place. The only contact between the two great civilizations was through 
intermediary traders
