Egypt's culture, government, societal organization, and civics had more commonality with the near eastern and Asian civilizations than it did with what's found in the rest of Africa so it's not out of the realm of reality to place a common origin hypothesis somewhere in the eurasian landmass, IF we want to let our imaginations stretch that far back. Aside from Nubia Egypt didn't have much interest or contact with the rest of Africa, they never felt the need to explore or contact anyone over there....all of their extended attention, trade, and correspondence was focused north and eastwards. Whatever "race" you want to believe the Egyptians were this is just the indisputable reality.
China invented printing, paper, and the compass...things that are crucial to how we live and operate TODAY. History, both ancient and modern, is replete with evidence of China's relevance. This is the type of hyperbole I'm talking about. Your over-eagerness to identify with Egypt is causing you to say stupid things.
