The educated classes in pre-European Africa were reading and writing in Arabic, Latin and Greek, just as their equivalents in Europe and the Middle East. I don't know too much about native sub-Saharan languages, but the idea that they couldn't express ideas or abstractions is obvious nonsense. I know two words in Swahili, one of which is the abstract 'freedom'. An article I recently read discussing various proposed (and probably wrong) origins of the word 'jazz' included the Mandingo verb 'jasi', meaning 'to become unlike oneself'. All human languages express abstract concepts and ideas.
Behind Eurasia, Africa is the largest land mass on the planet, and the whole history of pre-European colonisation is a long time. Nothing is universally anything in this history. Africa had dynastic Empires, centralised states and religious theocracies long before any Europeans arrived. The OP included links to a whole bunch of wikipedia articles, should you care to look.
So, the justification for European prejudice is... European prejudice.
Here are ust a few of the non-existent buildings the Africans were too stupid to put up by themselves:
Touchdown Caffeine!!!!!!!!!!! Thank you for proving my point! Also as for writing a language that could express ideas and abstractions...........you might want to check out the Ancient Uhuru and Captuba Tribes. Lets us not forget they have proven by satellite imagery that 5000 yrs before the Egyptians that the Nile ran thru the Sahara to the Atlantic Sea and now they are discovering Ancient Remains. There is also the fact that we know of 200 villages, towns and cities, lie beneath the Med. Sea and mostly along the African Continent as well as on the Atlantic Coast.........All predate anything Carthaginian or Phoenician and no Arabic or Persian sites located around the Southern Coast of Africa.
