Why when it was said that white people were the original, InI were labeled as savages who were "sub" human, animalistic, below the white man, entitled to nothing?

But now that the white man's science has proven that the Black man is the original, the white man uses the knowledge to claim some kind of entitlement to Afrika, its culture, religion, and land?

They are not seen as sub human, animalistic, savage....

It seems that whether they are out of Afrika or not, the white man thinks he is superior and entitled to all that is under the sun.
