1.While white Europeans did massively "white wash history", it is nonsense to suggest that ancient Russian and Chinese civilizations were "black". You have posted similar lies in the past about Mesoamerican civilizations, which you also have no proof of, and which all modern genetic testing refutes.
2. These "blacks ruled ancient Europe" lies are promoted by Afrocentric racists, who ironically perpetuate a kind of black inferiority complex (the idea that modern blacks are not respected enough, and so have to console themselves with the idea that they once ruled the entire world).
3. Humans only evolved white pigmentation about 28,000 years ago. So EVERYONE before 28,000 years ago was dark brown or black. But were there any human civilizations before the emergence of white mutations? No. The oldest civilizations are in the Middle East and Indus Valley (roughly 13 to 9 thousands years ago), at which point white people had been around for about 15 thousand years.
4. What really happened is this: 2 million years ago, homo erectus (a precursor to homo sapiens) traveled up from Africa and began settling in Europe. Homo erectus is generally agreed to be dark skinned (a very dark brown). They had no social organization, no agriculture, no complex languages or permanent settlements. They had no civilizations.
5. Homo erectus slowly gives way to homo sapiens. Then, 28,000 years ago in Southern Europe and the Middle East, mutations in homo sapiens begin to appear. They increasingly evolve white skin pigmentation as they adapt to colder climates.
6. So from 28,000 years ago onward, Europe is white. But note that there are no "civilizations there". Neither the dark skinned homo erectus millions of years earlier, or their white successors, built any "civilizations". Why? Because they were stupid as hell. Modern agriculture hadn't even been invented. Tribes were tiny and nomadic. They had no tools. They had no complex architecture. There can thus be no "black Europe civilizations" because even black Africa had not started its own agricultural civilizations!
7. Civilizations only started long after whites had already started inhabiting Europe. And most agree they started in Northern Africa, near modern Egypt, roughly 12,000 years ago. It's here where agriculture begins to be practiced, which in turn leads to the evolution of new forms of exploitation (bye bye women's rights, hello organized slavery!), social organization and governance. This civilization wasn't black like afrocentrists like to imply - the people would have looked like a mixture of modern Arabs, Greeks and Sudanese Africans - but they were African.
8. In the Indus Valley (north India/Pakistan), a similar civilization was forming. Genetic testing shows that they would have looked like modern Syrians or Persians. The first farming practices were also leading to the first civilizations in America, but these "mesoamerican" civilizations were not "black". They are more akin to Alaskans and Native American Indians, who arrived in the country not directly from Africa, but by crossing ice bridges linking Europe/Asia to Canada. Again, all modern genetic data confirms this.
9. Slowly, the principles of civilization and agriculture seen in Africa flowed north, up the Mediterranean, and into Europe. Europeans began practicing agriculture, and places like Russia would develop their first cities and then kingdoms in the mid 800s. So the idea that Russian civilization was "black" is nonsense. There were no ancient civilizations (black or otherwise) in Russia. By the time the first cities and kingdoms started appearing there, the dark skinned homo erectus was long extinct, and whites had long been the only people settled there.
10. Pretending that all ancient civilizations were "black", and that the "white man eradicated all black achievements", is such a lazy way to understand history. This obsession ignores actual black achievements, ignores how brutal and indefensible ancient civilizations (black or otherwise) were, and ignores the achievements of different cultures. The Afrocentrist conspiracist would have you believe MesoAmericans were black, or the Shang Dynasty in China was started by blacks, or the first Russian kingdoms were black, something which no serious historian, archeologist, or geneticist believes.
Just because racist Europeans painted Jesus white (if such a figure existed, he would have been dark skinned) because they were deeply racist, doesn't mean the first European Kingdoms were therefore black. That's a massive fallacy.
