There's no sand or any composite material. All solid blocks of stone weighing up to 1400 tons. We can't do that and we can't align anything to the cardinal points as precise even using modern gps and lasers. The great pyramid attributed to Cheops is actually 8 sided but you can't tell except from the sky on solstice.
And burn the scaffolding to fire the clay, I've heard of a similar system using burlap sacks stacked to get that "so perfect you can't fit a knife blade inbetween the stones" effect.
Even so, someone had to haul the concrete. Who built it?
Wait, who made the pyramids?
My theory is they used papyrus frames to shape the cubes and they made the vast majority of them using sand as some sort of concrete.
So all the perfect blocks are just forms like big bricks.

I'm pretty sure it's accepted that they had paid workers building things.
