I've never understood personally why people insist on alot of structures being built by aliens or with alien help. Advanced math and measuring isnt a new invention at all "after all". Or why people think only within the last 1000 years or so that "america" was discovered etc or that the world was flat (when the ancient greeks knew long ago the world was round even without using math, simple logic "they could see the masts of ships sailing over the horizon before they could see the hulls). Christopher Columbus enthusiasts should be shot out of a cannon in my estimation with those who claim "evolution is just a theory" (with no comprehension of the scientific definition of theory) he he My favourite is when people say Darwin was wrong on a lot of things so evolution is too, so was Freud that doesnt invalidate psychiatry or psychology har har har....
