The only races to have made any significant contributions to civilization are the Caucasoid and Mongoloid. While both were busy inventing and discovering great technology and innovations the negroids were either still living in tribes killing each other, or praying to gods their masters forced them to believe in.
The most probable explanation for their inferiority in so many fields is their lack of intelligence. The negroid has been shown to have inherently lower IQs (70-80) compared to the great mongoloids (108) and caucasoids (100). Before you spew the countless lies you tell yourselves (which are the only thing stopping blacks from committing mass suicide), it is said that "up to 80% of IQ is genetic, and scientists have found 500 genes linked to intelligence" https://www.newscientist.com/article/2163484-found-more-than-500-genes-that-are-linked-to-intelligence/
That is why you do not see any of your subhuman creatures working hard to get themselves out of poverty. What do you get when you put black kids in poverty? Guaranteed prostitution, drugs, crime, e.t.c. What do you get when you put EA kids in similar situations? Hard work and success.
This is also why you have no choice but to lie and twist history to fit your narrative. We only see black hebrew israelites, black Egyptians e.t.c. lying about history and trying to claim other peoples' history instead of making history themselves.
Imagine being the only race that cannot move forward. The ancient Egyptians, Arabs and then the Europeans made you their slaves. Inherently lower IQs, ugly facial features and dirty skin, just admit you are and always will be a slave race.
