What are some indigenous cultures or religions?

Your question is very vague, meaning that indigenous means "primitive" and the word "religious" derivates from latin RELIGION meaning "to tie fast" "To follow rules" "to fasten/to tieghten"......so, I dont understand your question very well.
If you want to know about primitive belifs, they are anything that reflects the sense of life; the sun, the rain, the thunder; they understood that there is someone above all creatinng the "whole" and they adored independently because they did not belive in monogamy, they thought everything is separate and may be they were right.
In regards to "religion" it is a latin wordl. Latin culture started in the 7th century, so it has not been on earth for long, meaning RELIGON has been an institution as for 8th century forthward. Religion is a powerful word in latin and the history says that it was used to tighten the people, to set them on track, meaning it has been a way to control. So I send back a question, what do you want to know?
