We are all crazy. Ever since we read the Book.
I believe that pokemons are akin to gods as they have godlike powers and some of them created the universe, time and space, the cycle of life and death, etc. It's less a religion and more an assessment of their power and almighty nature. Pokemons can get out of their pokeballs anytime if they wanted, they're only letting themselves get caught because they trust the trainer. They can understand our language. They are sentient creatures with a heart and soul and probably have more wisdom than humans as 99% of pokemons are kind. For me it's just obvious to recognize them as such. I don't know if that would make me an "Arceist", but I thank Arceus for his fine work and the perfect harmony he created.
I worship Arceus in terms of saying we're in a second universe made because Arceus wondered what would happen if the world didn't have pokémon except for the ones that allow the world to survive. A lot of legendaries and mythicald are still out there.
Also, I'm sorry my responses aren't as long as yours. I respect how you speak your mind.
Are you really believing that? Is that a genuine faith that you developed and feel in your soul? Because if yes, realtalk that would be quite interesting. You'd be the first person I've met with such a faith! I've never thought of it but I like it. How our world could actually be a second world created by pokemons. Or maybe it's just a different timeline, ha! Maybe pokemons will appear to live with us in the future. Nah, the alternate world probably makes more sense. And, no one can say it's impossible, after all! Who knows. Anything is possible. And my own otherworldly spiritual experiences have certainly shown me that there is "something else".
Another theory would be that by "the power of thought", those who created Pokemon in our world "willed" the world of Pokemon into existence in some parallel realm. And I'd have some evidence/experiences with "the power of thought" to backup that theory, like I noticed "crazy coincidences" that are like "technically possible magic" but just too mind-blowing that it's almost impossible to fathom that they would be just coincidences. Maybe if enough people were thinking/feeling the same thing, at the same place and at the same time... something could happen and we could will something into existence! Just food for thought.
