This is perfect if you're in school, maybe you're doing an assignment, maybe you have a test tomorrow, or maybe you're just cray cray on the internet. Either way, we're going to giddy up for the learning and we're going to go get her done right now. So as we discussed in the previous lecture on the Neolithic Revolution, kind of the end of the caveman as people begin to sit down and settle and relax and build stuff, we really get different pockets around the world. And one of those earlier pockets is in the Crescent Valley in the Middle East in a land called Mesopotamia. Now it's not like it's a country. It's not like people are like, hey, I'm from Mesopotamia, where are you from? Just kind of the area of the world that archaeologists and historians are going to be able to refer to so we know what we're talking about.
