Any example of either as a business is already a corrupt example, as they are at their core methodologies rather than games.
How do you figure that? Is that what most religions claim to be doing? Just as many confuse science (method) for technology (tangible results), many do the same with religion (method) and mythology (tangible cause). The disconnect is that 1. mythology functions as a metaphor, as storytelling rather than history, and 2. the mythology exists because it is used by the true purpose of religion, which is to discern and cultivate subjective meaning. Because knowing how and why the universe exists does not automatically help one to know one’s place in it, or find personal or cultural meaning in any objective phenomena.
Finding meaning in what doesn’t exist is how many fail at religion, but that is not a flaw of religion itself. Most people just aren’t very thorough or rigorous. And elites encourage the masses to be gullible, which I think is what the OP is getting at.
I am not sure if “supernatural” is a meaningful distinction. My experience is that people throw it about assuming that they know what it would mean. Most people I know don’t even agree about what is “natural” in the first place. So it IMO tends to lead to an infinite regress of people arguing for and against poorly-defined terms.
As an engineer, I have created several gods. It’s pretty easy, anybody can do it and it’s a lot of fun. But to me, the distinction between art and religion is a false one. To me, they are synonymous. Art and religion are no more nor less than techniques for understanding and communicating that which is completely subjective. But this generally happens in its deepest at a pre-verbal, symbolic level of consciousness. So symbols and artworks can and do incorporate things from the objective world. But just like literature, they are not meant to be taken literally. The fact that many misunderstand this does not change how religion works, any more than it does when many also misunderstand how science works.
