here is an Ancient Greek vase, I've seen the argument that ancient Greeks painted a lot of their figures as black even if they were white, but this one proves that theory wrong, there's also many other vases proving it wrong as well
Not only that, DNA wise Africans and Greeks share a lot a lot of traits, for example Benin Sickle cell, being more susceptible to Vitamin D deficiency, which gives credit to the argument that Greeks and Africans have more in common with each other than Greeks have with other Europeans ancestry wise
Also, Whites in America originally didn't even consider Greeks as white, the KKK targeted them. and there's lots of Ancient Greek writings of Greeks showing disdain for other Europeans, they considered them barbaric, stupid and behind the rest of "civilization" as opposed to Greek philosophers praising Egypt and being know to travel down to Africa and learn.
Why would Greeks have even have originally thought to have traveled down to Egypt (not having the access to even know what was going on down there) if they could have just travelled closer to their fellow Europeans and neighbors? Because Greece prior to Aryan-Greece was originally made up Of Africans who settled there
