>I notice you never provided an example of a tall building without reinforcement from those same regions and times. And why should I? What's the fucking point you fucken idiot? To prove that egyptian pyramids are unique? Yes they are, they haven't been built by random niggers/sandniggers Oh btw, pyramid of giza has been built in 27 years... <- 27 YEARS https://en.wikipedia.org/wiki/Great_Pyramid_of_Giza >Egyptologists conclude that the pyramid was built as a tomb for the Fourth Dynasty Egyptian pharaoh Khufu and estimate that it was built in the 26th century BC during a period of around 27 years.[3] Let that sink in you clod... One last thing, clod: ancient egyptians aren't supposed to have known about pi and phi, and they were supposed to believe that the earth was flat... There's A LOT you know nothing about when it comes to that topic....
