ok... what is all this..??
Similar Pyramids ALL OVER the world, by people who didn't seemingly know each other.
By constructions means NO ONE can explain.
Aliens... Thats gotta be it
> Similar Pyramids ALL OVER the world
That's what happens when you simply try to build tall things with minimal archtectual finesse... they wind up looking like piles. After the disaster of the "bent pyramid" the Egyptians discovered the proper angle for the sides fo their pyramids by simply copying the angle that a conical pile of sand takes naturally.
Not that complex to figure out.

Errrr... no.
I think you may mean "undocumented day laborers".
