I like what you’re doing, but thought that religion might work better as an alternative to the existing scientific structure than a new addition to it.

that could be interesting.  how would it work?

imo, cavemen lives in uncertainty. to deal with this they look for help from beyond reality but at the same time they are adapters and learn.

help from beyond reality can be represented in a religion structure where they seek protectors in the form of animals that maybe connect somehow to types of help or benefit cavemen get for worshiping that animal

and learning represented by scientific structure in place now

to be quite literal about this, in history science and religion were the same thing until the enlightenment.  people tracked the stars for religion and made science of the stars.  and so forth.  i don’t think cavemen should or would think of their research into the world of the unseen as anything separate from other pursuits.

Actually,    Having an invisible rule that suddenly pops into existence when a learn grunt with a certain name passes is both inelegant and potentially dangerous.

When my CfJ passes the learn grunt great sky eagle will be gone. Would be dangerous to have a proposal linger around when anyone can make a new learn grunt called great sky eagle

ooh, that could be fun—of course the learn grunt would still have to pass in order for this proposal to take effect.  but that could be fun, a lingering invisible rule.  nevertheless:  s/k
