The Inconvenient Truth.

[longly]

Originally, the Nile Valley was occupied by people with ancestry connected to populations further south in Africa. Their skin tone was probably brown, not extremely dark. Later—sometime after the last Ice Age—people with more Eurasian ancestry began moving into North Africa. There may have been conflict, as often happens in human history, but it is also likely that these groups mixed with the local populations. Over thousands of years, this mixture contributed to the people who eventually became the ancient Egyptians. This process may have begun around 8,000 years ago, although the exact timing is uncertain. Before written history Eurasian ancestry continued to enter the region in multiple waves, gradually influencing the population. As a result, the general appearance of Egyptians today is broadly similar to how they likely looked during the time the pyramids were built.
