Why do humans always tend to form some kinda occults about persons or rituals or whole religions..?

Why can't people just accept human nature (culture) and try to allign as much as possible with earthy nature.

Look at amazonas. What scientists call wilderness, might have been the biggest combinations of human culture and nature. Like big fat permaculture garden. Amazonas earth normally hasnt much nutrients, but terra preta has (and there have been found big spots of it) which is human made soil.
