“Abraham received man servants from Pharaoh in Genesis 12. It would be very possible that there would be Africans in his group.”
Africans, sure. African-Americans with a trendy fade-haircut? No.

To introduce people to the stories of the Bible?
Please. Everyone knows what is in the Bible, no one needs to be introduced to it.
