I think that it should be made very clear in all articles that mention Pokemon legends, such as the Sinnoh Creation Myth, that they are just that: Myth. The current articles treat these as fact. It seems highly unlikely that a creation myth that only appears in a single region would indeed apply to the entire game's universe. If these were indeed the origin of the Pokemon universe, wouldn't it make sense that these stories would be told throughout the regions, rather then simply a single region? Doesn't it seem more logical that these are simply just legends passed down through a certain region, and nothing more?
