Henotheism in the Hebrew Bible.

[Jehanne]

But what is the historical and cultural religion of Africa? Hint: it certainly isn't christianity.

Africa's kind of a big place. 

The Copts are in Africa, and they have a long history and cultural influence. 

Ancient Alexandria was an important center for the development of early Christianity. 

So some of Africa's historical and cultural religion is Christianity.

The Jews were never in Egypt, at least in large numbers.
