Therefore, everything that has existed, everything that exists, and everything that will exist are indirect creations stemming from what it directly created (the Universe, Dialga, Palkia, Giratina, time, space, the Spirit Trio, the soul, the matter). All living beings are composed of matter and a soul, which are the result of Arceus's creations.
Eggs inherit the traits of the parents, and there are males and females. When we say they appear magically, it's just a sanitized version for children, since they won't be talking about sexual relations in their games. Humans don't lay eggs.
Darwinian evolution is even confirmed many times in Pokémon through Mew, Fossil Pokémon, Paradoxes Pokémon, Regional forms, and so on. All are manifestations of the evolutionary process of species in their natural environment over a certain period of time.
In Teraleak, Palkia also possessed powers related to the sun, heat, light, and daylight in some versions. But this is irrelevant, just like the part about her connection to humans—it's dead.
There are no humans in the void; it's illogical and impossible because matter and the universe don't exist. Humans aren't divine entities existing outside of time, space, matter, and the soul. Regarding the part of the myth you mentioned, the world is already created by Arceus and the giant(s). It's only after the world is created that we hear about humans and Arceus in female form. This version is therefore completely contrary to the official canon and cannot exist.
