I'd just like to offer an idea: We mistake the extraordinariness of man's creations for the extraordinariness of man.
How often are we astounded by the creation (Annie Hall, The Cantos) and disappointed by the creator (Woody Allen, Ezra Pound)? It's because great creations, we assume, are made by great men / women. And since we're surrounded by great creations on a day to day basis (cars, computers, electricity, controlled fire, airplanes, cement roads, wooden houses, hospitals, etc) MAN must be great...nay, "in God's image."
I think man's creativity is more our specialty - like Darwin's finches, their specialized beaks based on their diet; or like the peacock's tail, or shark's rows of teeth - or rather, it's our TRICK to surviving, but it isn't proof we're highest on the hierarchy of creation. The cat probably sees how graceless most of us are and thinks CATS are god-like; dogs probably see our pathetic sense of smell and...well, you know.
Our creativity - we have such a complex language! (our creation) - is like a highly specialized organ, like a dog's sense of smell. Our creations are incredible, most individual human specimens, on the other hand, are quite canny, ESPECIALLY when stripped of their man-made objects (clothes, shoes, glasses, etc).
