As an "atheist", the aura of the psychedelic experience is bizarrely spiritual. I think I have some good scientific understanding of it, but it's still extraordinary. They could be considered a "gift from God", in a sense. There is something about the experience that inherently produces this feeling, and I think it's explainable.

I also just find the idea of engaging with religion as a work of fiction quite fun. Spirituality has been entertaining for the same reason I love RPGs. I'm a therian, but believe therianthropy has a science to it. Otherwise, I wouldn't be able to sense being one. However, the notion I was an animal in a past life, or had a past life at all, seems ridiculous to me. My brain chemistry is just bizarrely attuned to nature in comparison to others.

So indeed, mushrooms do exist, and they could be the closest thing we have to a God. I don't know if that's the best explanation, but that's just my perspective.
