How would you know if we did? our history is oral and racists like napoleon would rather kill himself than admit that blacks or anything non white could build an empire. I get what you mean and i hate our arrogance to but you have to take into account that our history is really a mystery (rhyme not intended). No one has ever excavated in somalia and we have no knowledge about what our ancient ancestors did besides what the greeks wrote and no one can really verify it. Just because the current generation of somalis are retarded that does not mean all generations were form the beginning of time, smart ppl will acknowledge that until evidence is gathered against a hypothesis with certainty then you can never completely deny it.
In my opinion if you don't have an alphabet you're irrelevant.
