It is man, and man alone, who says anything that is said. Unless, as has been noted, you do have a talking frog in your pocket. And I don't see where you would get an implication like that - man's moral nature might placed at any number of places in a hierarchy, depending on who's inventing the thing. If bees made a hierarchy of moral natures, I could easily see them putting a being that allowed dozens of queens per town to breed and forced drones to work pretty low on the hierarchy. Hierarchal description is a human invention, yes. Nope. I am observing that only humans make statements around here so far as we know. Whether that makes humans "above" anything else, I don't say - it strikes me as a goofy question. What hierarchy are you assuming? Whether there are other beings making statements somewhere or somehow, I don't know - my guess would be "yes".
