How did geographic conditions limit contact between africans and people from outside of the middle east?

The geographic condition that was a barrier between Africans and people from outside of the Middle East is the Sahara desert. Furthermore, historically Sub-Saharan Africans weren't noted for their traveling or exploring abilities, so that's another limit to the contact.

answer: it was the day wean all the sadness went away, you took me off my feet before i knew who you were, you look at me with not knowing who i was i wish one day you would to, siting here with none there hoping you would see me from the distance, daydreaming about what we would be or not to be, but in that moment of doubt you cam to me with a small worm smile and said: you are the one i have been looking for all this time, and wean i saw you cry in that moment i would have had a great sight wishing you would talk to me the first day we meet, so that we would be blessed i'd wish we cam sooner to this point my love and he said: my love.
