As people became more sedentary during the Neolithic era tribal groups united forming larger populations. These disparate groups, to form a functioning society needed to share a common sense of the way things are, a shared belief system. They needed a storyline that all could grasp, accept and believe in order to accept a hierarchical structure to deal with property ownership and exchange of goods.

A workable storyline would need to include reference to the supernatural. Human uncertainty requires connection to an entity that can be appealed to when crops fail, drought occurs, or outsiders threaten the groups existence.

As societal stability evolves, multiple story lines will develop, one flexible and open to new developments, another rigid, protective and resistant to change. Hopefully stable institutions will be in place at that point to accommodate such diversity of thought.
