Yes. While europe was trying to come out of the Dark ages, the Kingdoms of Ghana and Mali etc were teaching the rest of the world. Matter of fact those times produced great art better than anything in europe and the wealthiest man to ever walk the planet.. They also learned how to make carbonized steel. They dont tell you this stuff in school so you have to look for it.
Yeah, we see how the Blacks have advanced all over Africa. Remember, if you ever get sick, do not use anything which was thought up by an evil White man. Why are you even on your computer? A Black Man didn't invent it. Meanwhile, there are still Black tribes in Africa still murdering each other, like in the Dark Ages. I guess by some Blacks that would be called Advancement.
