No, i would say it’s very similar. Pilgrimages, a priest class, specific buildings to worship in and “sunday school” of some form or another. If you disapprove of modern religions but like the old ones then it’s really the content of the religion you have irks with.
Early “shrines” in Mesopotamia were about making a landmark to find and return to and rebuild each time they came by (which isn’t necessarily a “pilgrimage”, just knowing where to return), and then building large storage rooms for all the grain that could be redistributed to the people. We don’t have any particular trace related to sacrifice or teaching worship, or even any mark of distinction between priest and non-priest class, as this was before writing.
