ELI5: How do temples on top of mountains or cities built in the side of cliffs get their building materials to these remote locations?

It can’t all be carried by hand, can it?

Short answer, yep, labor. Enough humans, with enough time, and enough motivation (money, religious conviction, slavery, etc) can move  an almost unimaginable amount of material. 

Of course we've harnessed beasts of burden, but when it boils down to it, 100s-10,000s of people, with enough time, can build amazing things.

Think about it, a dude can carry a 50lb block, 10 dudes can wrangle a 500lb block, etc etc.
