Are you sure your timeline is correct? Assyria as an empire is closer to -1400 to -700, with the dominant part coming after -1000. Similarly, there was no "Mesopotamian empire" in -4000 that I'm aware of: before -2000 I think it was mostly city states all around the near east.

I'm no expert… please correct me if I'm wrong.

Their timeline is definitely incorrect beyond Rome. "2000 years before Rome" was the period of dominance of the Akkadian Empire of Sargon, and right afterwards of the Sumerian Third Dynasty of Ur. You are correct about Assyria and the Mesopotamian warring cities.
