The mysteries of religions

Why are there so many religions?
one for every culture.

They the faith grows like mushrooms
in a glade after rain and rot.

Disappear into the forest floor and
a new religion emerges from the soil.
                      
                      
Fertilized by prayers and rules made
by those who see them self as clerics.

Many of those who believe in this fantasy
are ready to die for their faiths.

Mushrooms in the dell keep growing
but we turn a blind eye to their demise.
