Why do whites deny the fact that the Kemetic were black?

the word Kemet means black but the white ecologist claim that the early were talking about the soil in Kemet and how it's fertal meaning "black" that makes no sense to me at ALLL!! is t a racial thing? why cant the scientist make it a fact (which it is) that one of the advanced and the first civilization was black/african the evidence is right in their face!!! they Know whites originated from Europe they know that the first person on earth was a black woman or man in africa. the kemetics even admitted that they traveled up the nile from Ethiopia and Ethiopia a really black african country! upuntile the romans took over why isn't it now fact that the first Kemetics were black. if you don't know who the kemetics are don't answer this questions )=(
