PLS HELP!!!! I NEED HELPP
I am doing an assignment about researching the Mesopotamian civilizations' years of existence, and everytime I search up any of the mesopotamian civilization's years of existence, what comes up is the years of existence of mesopotamian empire. So, I want to know if mesopotamian civilizations are the same as mesopotamian empires. If not, what should I search up to find the results I'm looking for?
