I definitely feel that they are presented as human. But I am struggling to find any hints even, let alone definite statements of their species. Sure they call each other "people" or "man" and "woman", but is that enough? Does anyone know how this can be determined? Or is it possible to put them as human because River never commented on them not being human?
