Is Mew or Arceus a god Pokemon?

Answer 1

One opinion believes that Arceus cannot be the God of Pokémon because it cannot learn every move.

However Mew also cannot learn every move in some Pokémon games.

Another OpinionAccording to the Video Games, Arceus is implied to be a God according to the tales of legends and beliefs with no absolute confirmation by the developers that says it is the God of Pokémon. There are even Pokémon like Mewtwo, the Porgyon family, Clefairy, Deoxys and Castform that are either man-made or come from a different universe than the one known universe in all Pokémon games, movies, graphic novelsand anime. Another OpinionAnother opinion believes that regardless of Arceus having the highest base stats, they don't believe its high stats mean that it's a God among Pokémon despite being a powerful Pokémon. Another OpinionPokemon mythology clearly states that Arceus was born from an egg that sprung from a shapeless mass known simply as chaos. Once born, Arceus then proceeded to create Sinnoh and arguably but very likely, the rest of the Pokémon universe. Also, being the "God" of all Pokémon by no means entails being able to learn all moves.
