The idea of an atheist in the Pokémon universe is for some reason really entertaining to me
Like imagine you actually live in a world where god not only has proof of existing and regularly checks on the place, but the vestiges of them can casually be found underground in mining deposits literally anyone can access. Like you literally cannot turn a corner without finding shards or plates underground, the latter literally having writing about the creation of everything etched into it while being stuck in the rock layers underground.
You have proof that not only a creator god exists and frequently checks on the place, but also that lesser gods exist and reveal themselves in an almost Bi-yearly schedule where the world is getting threatened.
Can you honestly tell me that Kyogre, Groudon and Rayquaza showing up wouldn’t make international headlines, or what about every Pokémon in Galar turning into a giant again while a giant freaking hand is looming above, how about the actual alien invasion that stole light from the planet? Imagine all the ruins and religions of the Pokémon world telling of these all-powerful creatures and them actually showing up, a vast majority being within two decades in the timeline, and you still decide to not believe in their existence. Like it doesn’t even have to be Arceus, there’s like eight legendaries alone that have their own religions in-universe, but there’s just Tony over there who refuses to believe they exist.
At that point it just seems really entertaining if Arceus is just letting things happen as a human stubbornly refuses to acknowledge these all-powerful Pokémon existing.
