All right, let's see if we can't build a civilization. I'm ready, are you ready? So we have a winner. We have the first earliest civilization that archaeologists and historians agree is Sumer. And of course the people living in Sumer are Sumerians. Never met a Sumerian, but they did exist. And you have to remember that it took a long time to get to the point where we could have a civilization at the end of the Neolithic age.
