In the Diablo video game series humans are the offspring of demons and angels who were tired of fighting each other. I thought that was mildly clever at the time but it seemed like it had been done before. I could never find any earlier examples though. Seems in most fantasy humans are created ex nihilo, or maybe we’re a degraded version of the ancient superior progenitor race, or maybe demons OR angels made us. But not both.
In the other Blizzard universe (World of Warcraft) humans are diseased descendants of stone giants that were seeded by the progenitor race.
South Park - earth is an intergalactic reality show, seeded by species from many planets. Human ethnicities are different species from different planets.
ETA: crap, didn’t notice (or expect!) that the above link mentioned it.
On Krynn the god of Good created Elves to embody order, the neutral god created Humans to embody free will and the evil god created ogres so she could exploit them.
