Try to take your fairy tale religious nonsense out of it and look that the question of civilization from the lens of anthropology. We Somalis were given this name "somali" from the British explores who sailed from Yemen to Berbera. The name "Somali" comes from So-maal which means to "go milk". The country Somalia was drawn up by the British colonial office, we had nothing to do with it really.
As for Babylon, yes Cushites could extend all the way up to the Tigris river and founded a city called Babylon. The language is very similar to Cush or Nubian but not Arabic as this came much later. The Arabs do not have a history outside of Islam (founded in 630 A.D). The Arabs invaded most of Mesopotamia some 1400 years ago with Islam which is not civilization but a book based on faith and not science which is what the Babylonians had been doing (Astronomy, mathematics, Agriculture, Code of law). So don't confuse Arab with Babylon or Sumerian as these people were much different to the president day Iraqis, Syrians or Jordanians. Think of the temperament of the Arab and ask yourself could these people build a pyramid or Ziggurat? But the Cushites could not because they had dark skin? does this make sense?
