Pure Speculation?

I read somewhere on the internet that some Luhyas came from Egypt and so did some Baganda and oba Banyoro. I thought all Bantus came from Congo or Cameroon. Speaking of Congo, I read somewhere that the Ethiopia referred to in the bible included the area stretching from the Congo basin.

Another mind boggling thing I read on the internet is about the Wanga (a tribe of the Luhya). I read that the Wanga came from Egypt as part of the migration that settled in Kampala area that formed the Buganda Kingdom. A muganda Prince called Kaminyi, who was Kabaka Mwanga I's cousin and Kabaka Mawanda's son, fled to Tiriki in Western Kenya. (Incidentally, I lived in Tiriki with my parents for 8 years) The Prince fled because as the king's cousin, he posed a threat to the reigning monarch.

On reaching Western Kenya, the Prince became a ruler and was succeeded by his son Wanga who established the Wanga Kingdom with the title of Nabongo in the 18th century.
