What religions were there in Africa in 1600s and 1700s?

they were and still largely are tribal.

that time period was before modern day christian outreach work.plus,a lot of people would get killed just for showing up.jews and arabs lived in the Middle East and were still busy trying to fight over thier own land.

Hinduism and Buddhism were in the other parts of asia.these also include taoism,shintoism and ja'inism.

what im getting at is they were still worshipping the river.
