Why are you disagreeing with facts, genetics & historically accurate information? What is your motivation to hold onto foreign lies about African culture?
No, because there is no continuance of ancient Nile valley culture.
Point 1
Most of Africa did not worship any of the ancient "gods" besides what is today northern Sudan & Egypt. Dinkas did not worship isis nor did fulanis, kikuyus, oromos, Zulus among others. They had their own beliefs systems which many people here pretty much ignore
Point 2
Where is the evidence of hieroglyphics writing or something equivalent?
Point 3
Have cultures such as Zulus among few others(not all of Africa definitely) once lived in advance system and resort to living a much simple existence?
You can keep diluting yourself, but the fact of the matter, the people who live in today's northern Sudan and Egypt whether supposedly mixed or not are descendants of the ancient Egyptians. The evidence is daunting. Any other group outside the region I mentioned is mere speculation. However more research have to be conducted whether other people across Africa that facilitate the civilization of the ancient "Nile valley. Which monuments and ruins is in Northern Sudan and Egypt today.
