It's hard for us to imagine how much has occurred even in the last 100 or 200 or 1,000 years, much less 200,000 years. But we seek to understand regardless. That is what history is all about. As we'll see, history is in general trying to understand the stories of our past. And if we wanna get a little bit more technical, we can also think about prehistory, which is technically the things that happened before we had writing. Because writing is our main tool for history. What I have right over here, this picture, this is Egyptian hieroglyphs.
