What happens if we find bones else where, which seems to be happening, and they don't relate to the bones found in the Afar region?
Then we find bones that belong to hominids that we had no clue that existed.
Years ago I read a book, “ The Washing Of The Spears”, about the Zulu, Bantu, in South Africa. It seemed that they arrived at the Orange about the same time as the Dutch.
The author stated that they had centuries to occupy a Continent but were to slow.
This peaked my interest and I did a lot of reading. The Pygmies where in Niger during Pharonic times, Herodotus, “The Histories”.
Another thing that caught my attention is that the Bushmen, the Hottentots, and the Adman Islanders, for example, seemed to have been pushed South West and West by pressure from the North East, I have no theory but it seems strange.

Yep. That's the problem with "science by media" which appeals to the egos of many current researchers. I think much of this "Out of Africa" stuff began with the Leakeys who hyped their work via National Geographic Magazine. NG, as we know, is as politically correct as it gets.
I look at the vast areas of Earth's surface that haven't yet been systematically investigated and common sense tells me we know only a little of the human origin story.
