How does any reasonably intelligent society NOT have a rudimentary idea of “wheel”? I mean, all they had to do was have a tree trunk, and something fallen on it, to see that it is easier to push the thing with the tree under it, “rolling” along.

Remarkable, IMO, that no artwork has (yet?) been found depicting how the pyramids were built.

who had time, they were all hauling rocks around. Amazing that no other country just invaded while the entire population was wasted building pointy structures.
