Whether or not the noses were intentionally destroyed or not it is most parsimonious to believe that the indigenous people of Egypt were African people. Thinking they werent would be like looking at the population of The United States today and believing the Native Americans were white (and if we didn’t have photographic evidence of the natives we can be sure that would have been suggested, and if anyone suggested otherwise they would have been met with “what a crackpot theory!”).
In either case, the Europeans revered ancient Egypt for sure. But this is only because of their mention in the Bible and their interaction with the Ancient Greeks. But when Western Europeans got there, the people who lived in Egypt looked more like them than Africans. But this is only because of the displacement of the indigenous population serval centuries earlier.
