Or you could just look at a timeline
the Arabic invasion & the incoming of Islam to East Africa in the 7th century did the same damage to the continent as the european invasion of 1492 & the spread of Christianity. It is what it is
I think it's best to not even take dude serious bro, look at the join date, the screen name and obvious troll factor, coupled with most of 85% of his post since he joined happens to be in this thread and you have the makings of a troll. To say what does it matter that Jesus was brown, black, purple etc, but then argue the point that he was anything other than black/brown (which people of African descent come in all those shades) is intentionally undermining not only historical and biblical accounts, it also defies common sense. It matters enough to the scholar's looking to keep up the fallacy that the Hebrews, Moses, Jesus and Egyptians weren't of African descent; even though there is a general consensus among their own scholar's that Egypt was predominately African to admixed until the end of the dynastic period generally.
As far as Africa not having any influence outside the continent of Africa, might want to do some honest research, instead of looking to troll. There has been Egyptian artifacts found in the Grand Canyon back in 1909, not to mention the Olmecs being of African heritage, along with an African presence here in North America way before
Columbus "discovered" America. So yes it's important enough to those who have evidence of the historical aspect of the bible and African civilizations and history to suppress and even erase it from official records. Because to them its obviously important enough to try to squelch, so it should be important to any person seeking real truth to learn and understand why.
