Since I don't want to derail the mega evolution thread, I'll address this here:
----------
it's abilities are down played obviously but even then it is still the most powerful pokemon that essentially created the universe according to the legend that the people had faith in
----------
The problem with this is that we don't even know if the myth is true. People in the games can't even consistently say what it was Arceus created; the Sinnoh region, the Pokémon world, or the entire universe. Cynthia, who studies these myths, says that the myths are likely just misinterpretations on the part of ancient people, and the the Pokémon involved aren't really what they are purported to be. So even if people believe in the myth, that doesn't mean it is true.
----------
now mew is more akin to Adam or the " first man" archetype....it was the first pokemon created by arceus and it provided the genetic basis for all the species we see today
----------
And then the problem here is that Mew and Arceus were never said or implied to have any relationship whatsoever. That is just the fandom's attempt to resolve a non-existent "paradox" between their respective myths by forcing the two of them into a Judeo-Christian narrative mold despite neither being inspired by Judeo-Christian theology.
If I come off as hostile, I apologize, as that is not my intention. I just wanted to respond to you without disrupting the thread.
