There really is no legitimate proof of which one came first. I mean, if Arceus did create Mew, then Mew wouldn't contain the DNA of all Pokemon because it's missing Arceus's DNA. If Arceus was the one who gave birth to Mew, then Arceus would too contain the DNA of all Pokemon. But yeah, there's not enough of the story to determine which came first.
~pokemon pearl~it is told in mythology that this pokemon was born before the universe exsisted
~Diamond/Pearlbecaust it can use all kinds of moves, many scientists belive mew to be the ancestor of all pokemon
It looks like it is based on a fetus. Which makes sense in a way since it's linked to all pokemon
No, Arceus created Mew. :P
Anyways, it looks like a Kangaroo Mouse (a type of mouse), since its face looks like it mouse's head. Its entire body looks exactly like that type of mouse also, and Mew sounds like Mouse (kinda, they just start with M). Although, it seems like a cat also, and sounds like Meow... It could be a bunny, which is an option.
i noticed that it has the tail same as eespeon.
as definied from pkmn diamond/pearl, arceus is the god of pokemon he created the world then dialga and palkia and so forth. so tech. me cant have all the dna of of all the pokemon in the world
I tink the best answer has ben a fetus so thats what I think it is.
Okay, maybe I should have put Earth in bold letters. Its the ancestor pokemon on Earth. Arceus does not live on Earth.
