But my hair's pretty flat today. So we're going to go with that they were just an incredibly advanced early civilization that was able to figure out the mathematics, the algebra, the physics of actually creating these awesome structures. And of course this is where the pharaohs are going to be laid to rest in order to have their internal spirit, their Ka, reign forever and ever and ever. But the most important lesson is that in order to do all of that, you can just imagine the advanced governmental systems that had to be in place to run a job that big. So make sure that you get the pharaohs and of course the big idea of the pyramids as we move on and we take a look at the religious life of an ancient Egyptian living in the Old Kingdom. I'm going to go get that right now. So like Mesopotamia, and perhaps because of Mesopotamia, you have to remember that the Egyptians are in contact with Mesopotamia.
