I have seen the incredible story of Coral Castle. This sheds some light on it! However, let’s talk pyramid of Giza!
You would laugh at my theory, which I have been stating for more than a decade, that most of the blocks were pour in place, with only the most prominent blocks (like in the king’s chamber and the pyramidal top stone) being cut and moved into place.
I saw something on one guy who showed how to lever a block up four feet.
If you can raise a block four feet then push it forward four feet, then you can stair-step blocks up as high as you want.
