But I will refer to the kings as pharaohs throughout this video just to say, hey, these are the Egyptian kings. And the Old Kingdom is probably most known today in our popular culture for what we most associate with ancient Egypt, and that is the pyramids. And here, right over here, are the pyramids. This is the Great Pyramid of Giza, which is near modern-day Cairo today. This is the Sphinx. And they were built in that old period under the pharaohs Sneferu and Khufu, right over here in the 26th century, right over here in the 26th century BCE. And we are still trying to get a better understanding of how this was done.
