Also, a three mile long ramp.
I like to ask my students how they think the Egyptians did stuff like this. They usually guess something like "a wooden thing with rope and they pulled it up." It's hard to comprehend how much effort Egyptians put into their projects. Building an enormous ramp and then tearing down an enormous ramp? That's a lot of shoveling.

Egyptians also used the "build an earthen ramp to get the heavy stuff up, then clear the dirt away after you're done" strategy to build their ridiculously awesome temples. Any History Channel fan knows that.
Just goes to show you how powerful bread is. Egypt had great harvests on a regular basis, something few other places could accomplish, so they were able to spend more time developing knowledge. "Western Civilization" was born in Egypt, don't let anyone tell you different.
