Well professor, I hate to break it to you that Machu Picchu is in Peru, which is here: and this discussion is about the United States, which is here: You're not on the right continent, or even the right hemisphere LOL! Also, Machu Picchu was built in about 1450. Sorry but it wasn't an "engineering marvel" and Europe's architecture and engineering was far more advanced than that of Machu Picchu by 1450. Machu Picchu is nowhere close to what was being built in Europe in 1450. You've been listening to too many liberal professors who try to downplay the accomplishments of white civilizations and exaggerate those of nonwhite civilizations. Further, the population levels are by no means a measure of social progress. Even today the 3rd world shit holes outnumber the populations of other developed nations by hundreds of millions, so that means south america, and sub saharan africa are "more advanced" than the developed world because they are more populated despite the fact that they are 3rd world shit holes? LOL! You fail, miserably, on all counts. The "engineering marvel" of Machu Picchu: European architecture of the same era (and some earlier): Machu Picchu was an "engineering marvel" compared to European achievements of the same era? LOL! Let me guess, next you're going to tell us how George Washington Carver was a "brilliant scientist"?
You are racist swine. Those are doctored pictures. Sad you'd stoop so low as to impugn the dignity of our 3rd and 4th world brethren, without which we'd still be living in caves. Here, your people
