What a bunch of eurocentric nonsense! The arrogance of those who believe that other people besides Western Europeans could have done something in terms of architecture and science without the help of some Supermen is appalling. 4 to 5,000 years ago the Egyptians were able to draw straight lines and to determine the height of objects with simple geometry. Using those skills, they built immense monuments. They had established literacy. Europeans on the other hand were sitting around picking lice off each other and trying not to starve to death.
