Im not trying to debate the Great pyramid here at all. Im simply saying it's so great an accomplishment that no one would believe they built it back when they did if it wasn't still there and only documented in few texts.
There's nothing particularly fantastic about the pyramids.
It's a pile or rocks.
No need for aliens. No need for magic. No need for Jesus. Anyone can pile rocks.
Yes, it's a lot of rocks. Yes, it took a lot of people. Yes, they did an excellent job and got it done relatively quickly.
It's still just dragging rocks and stacking them.
If the Great Pyramid had be build so that it stands on its tip, then THAT would be something that people could marvel at!
