It’s the disease that makes rabbit have red eyes (very easy to spot from far away). But beware, I’m storytelling from memory, huge details must be wrong.

This is a pretty stunning standard. By this standard, most of Africa has no native population. Most life anywhere would not qualify as "native".
Hominids have been in Africa for millions of years, but the Bantu Expansion is just a few thousand years old. It is younger than recorded history -- we have Egyptian records of the peoples to their south, with whom they traded; those people are extinct today. The Bantus reached South Africa at about the same time Europeans did! They colonized it much more successfully, though, largely wiping out the Khoisan who were there before.
