Answer:
Whats funny about this problem is that, we don't even really know if humans were created in Africa. It's a theory based on the oldest known fossils, but we will really never know where we originally originated at.
I assume that by telling this person this, this could change the person's perspective on how they see Africans, however even though Africa theoretically was the birth of homo sapiens that doesn't mean the original homo sapiens living in Africa are they same as they are today. People groups and ethnicities change a lot.
