ancient mesopotamia

What if the Gutian Dynasty of Sumer had never existed?

The Gutians were a people near ancient Mesopotamia whose language remains unclassified, who ruled Mesoptamia for about a century before the rebellion of Utu-Higal and the eventual prominence of the city of Ur, taking advantage of the kiloyear event to invade Akkad and install their own dynasty...

Your challenge is to have Ancient Mesopotamian culture survive to the present day in some form. It can be significantly different, as long as there's clearly some influence from Sumer, Akkad, Assyria, Babylonia, etc.
