First, prove to me that the ancient Egyptians were raw Africans. Once you prove this to me then we can proceed with your questions. I can't answer questions that are based on the wrong (or at the very least unsubstantiated) premise.

The following is one of the most recent scientific papers which prove that ancient Egyptians were black Africans.
Here I have quoted some conclusions from the paper.
(Sonia R. Zakrzewski. (2007). Population Continuity or Population Change: Formation of the Ancient Egyptian State. AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY 132:501-509)
"The raw values in Table 6 suggest that Egyptians had the super-Negroid body plan described by Robins (1983).. This pattern is supported by Figure 7 (a plot of population mean femoral and tibial lengths; data from Ruff, 1994), which indicates that the Egyptians generally have tropical body plans. Of the Egyptian samples, only the Badarian and Early Dynastic period populations have shorter tibiae than predicted from femoral length. Despite these differences, all samples lie relatively clustered together as compared to the other populations." (Zakrzewski, S.R. (2003). "Variation in ancient Egyptian stature and body proportions". American Journal of Physical Anthropology 121 (3): 219-229.)

So this recent peer reviewed paper proves that ancient Egyptians had tropical body plans. Arabs, Europeans and Indians or Chinese have no tropical body plans because they did not evolve in the tropics. Just to educate you about anthropology (I doubt you will understand this with that low reading comprehension of yours).Tropical body plans correlate with dark skins.
Produce a recent peer reviewed paper which has debunked DR Sonias conclusions, that ancient Egyptians were black Africans if you cant, then quit and go and educate yourself.
Again I repeat , repeat, answer the following questions:
1) Who wrote the oldest mathematical and medical text (still intact to this day)
2) Where is the oldest and still standing stone building in the world?
3) Who invented the alphabet and the calendar we use today?
Please provide the answer to these questions, tell me and we can continue educating you, otherwise, hide your tail and run!!
