"Man, born from dust, was strong, wise, and resourceful, but he was born into an unforgiving world. An inevitable darkness - creatures of destruction; the creatures of Grimm - set their sights on man and all of his creations. These forces clashed, and it seemed the darkness was intent on returning man's brief existence to the void."

If man was born into an unforgiving world, then that would mean grimm existed before man or at least some time before man's creation. Artificial creation is plausible but the creator can't be human.
