The Egyptian pyramids are truly fascinating.
They documented EVERYTHING, but how they built these incredible structures? Ok.
But the structures in Cusco Peru are even more fascinating.
Stones as big as the ones in Egypt, and fit together just as well, but are irregular shaped.
How do you do that with sticks?
Bus sized stones quarried from the top of one mountain, crossed a huge lake, and used to build a temple on the top of another mountain. All before math and written language, and before the wheel!!
Seriously?!?!
