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. And Egyptian hieroglyphs are over 5,000 years old. So you could write 5,000 years before the present. But even when you have writing, it's not enough.
