It's Pokemon entry implies it's still uncertain if it's true.
>Its DNA "is said" to contain the genetic codes of all Pokémon, so it can use all kinds of techniques. >Because it can learn any move, some people began research to see "if it is" the ancestor of all Pokémon.Just like you quoted in your post, but It's the same thing for the creation trio, they're both vague, but as each generation comes out everything gets retconned by newer entries.
And yes Arceus is a Pokemon but It was never born in any region nor in the world unlike Mew, He clearly has his own dimension, in other words he's not from this world just like Deoxys and the creation trio.
Or Necrozma, It's clearly an UB yet it's considered a Pokemon because people think that anything that isn't a human, is a Pokemon.
So even if Mew were the ancestor of all Pokemon from the world, because that's where it was found, it isn't the ancestor of beings that live in other dimensions or wormholes.
