Nah dude, religious rituals and the hierarchy associated with them is as far as we can tell a post-neolithic invention. Humans existed for hundreds of thousands of years without priests telling them how God wants them to act, whether ritually or in social settings, and we could go the next hundred thousand years without them and it wouldn't be a problem.
You're crossing some lines here between worship of a deity, priesthood as a social role, and religious rituals themselves, all of which can be found very independently of each other. The existence of religious rituals does not necessarily imply priests, gods, or hierarchies.

You mean back before the agricultural revolution and people started living in societies. I think ritualised religious social groups will be fine
