>>1837050Well, it's a little more clear why if you consider what you're actually advocating. We'll take "religion" in this sense to mean "unified belief system that involves at least some supernatural claims." Obviously no such beliefs are emergent among people who share a love of the outdoors worldwide (and don't share nation/culture/language/etc), or a religion would've arisen naturally.
So what you're really asking is,
>Why has nobody invented a religion, involving contrived beliefs that nobody has any reason to believe, to unify all nature-lovers into one spiritual group?To which the answer seems obvious: nobody wants to do that you fucking dumbass, that's the most inauthentic, disingenuous and forced thing anyone could possibly imagine doing. We're unified where our values are unified, divided where our values are divided, and stuck with both because our values don't come purely from enjoying hikes. That's it.
