How to build a pyramid!

There's a lot of speculation as to how the ancients built the pyramids, most use ramps. Some speculate that ramps couldn't hold the really big stones or would collapse. Really the better way to do it would be to mud the entire base. Create a hill of mud up to the top of the pyramid used thus far. So rather than any sort of special ramp, you'd pretty much end up with a mountain of mud, then when you're done, just dig it out. It might require moving a lot of dirt, but it's well within the abilities of peoples and it would never collapse under any amount of weight. Put some rocks in place, build a hill, put some rocks in place, make the hill bigger. You'd largely end up doing that anyway. Especially as you need to lift the stones up higher.
