Every species is created by a god. A god who designed their homeworld, its fauna and its people. As such, each and every species in the multiverse is endowed with special powers from their god granting them unique abilities. Something that puts them ahead of others and creates their own unique niche among the various people in the universe. Humans don't seem to have any of those. They have no sharp claws, no hides that can deflect bullets, no abilities to see into the arcane and mold it to their will. In terms of intelligence even other humans seem to think the average is low and their perception isn't that much better. It is a question how humans even manage to differentiate themselves from wild beasts, seeing as how there is nothing magical to set them apart. Much less how humans will manage to survive the cold and uncaring universe at large without being conquered and made subservient. But then for whatever reason, humanity's God is the only one who melts people's eyeballs out of their skull when they look at him so they might not do to badly after all.
