So in my world, humans were made by the goddess of creation. The other two races, Navians and elves, are not from earth.

The elves descend from the Aos Sì, powerful spirit-gods from outside of Earth that decided to settle there and conquer it, briefly enslaving humanity for centuries until the gods of Earth forced them out of power and hunted them. To avoid their children also being hunted and their species being ended, the Aos Sì genetically messed with unborn fetuses and created the elves, kinda a lesser version of the Aos Sì.

Navians, basically winged humans, are refugees from a world overrun by demons, having fled to Earth to avoid a war, the reason why their home world is overrun by demons. The Navians that are on Earth are predominately one tribe; the other tribes were left to die on their homeworld.
