"The way I see it, our world began when the spirit within people was born.
When that spirit came to be, there followed awareness about the world.
Within the newborn spirit, time and space were intertwined as one.
People and Pokémon, too, were but the same presence.
As I understand it, people and Pokémon shared the spirit and awareness.
They should have understood and accepted each other then.
Because they shared the same spirit, people and Pokémon intermingled.
People took the place of Pokémon, and the opposite also held true.
That interpretation could give us an idea about how our world came to be.
A Pokémon is said to have shaped this world.
Could that Pokémon be the physical form of the original spirit?
Hmm... The spirit came to be, and from it, time and space were born...
That seems to point to Legendary Dialga, the Pokémon of time, and Palkia, the Pokémon of space...
And they lead back to Arceus, the Pokémon that made them arise.
Oh, there were also Plates, weren't there?
One Plate read "Three beings were born to bind time and space."
Those three beings I read to mean the three Pokémon of the lakes. It's about Uxie, Mesprit, and Azelf.
The myth describes how they gave spirit to the world, shaping it.
But it all starts with Arceus, the first. It is known as the Original One."
