Historians proper get so caught up on the ramp, but by any metric they seem ridiculously unfeasible.<p>I don't know why they are so quick to throw out the Herodotus Machine, where you rock the block back and forth and place shims under it. They don't require lots or resource or technology, or a backbreaking amount of labor, and two people can move a single block - taking as many breaks as they need to. And you know, it's how the locals told Herodotus it was done!<p>As opposed to a ramp that's bigger than the pyramid itself, take an insane amount of uninterrupted work to haul up, and there is no archaeological evidence to support.<p><i>Edit</i>: Here's an example that seems to fit Herodotus's description: <a href="https://www.youtube.com/watch?v=4hLQoD3Cwag" rel="nofollow">https://www.youtube.com/watch?v=4hLQoD3Cwag</a>
I see no reason to believe that anyone sophisticated enough to design a pyramid wouldn't be sophisticated enough to stack shims.
