Hmm... I'll get back into a creationist's shoes for a moment: if God is the creator of everything, including every living being, why should the specific human difference (unprecedented development of the symbolical function in speech, facial expressions, gestures) be more a proof of creation than, say, the spider's web or the bat's "sonar"?
Now insisting on the human difference would make sense if one assumed, in a Gnostic way, that there is something in man which does not belong to the realm of creation. Unfortunately the many evidences of continuity between species in organic structure and function do not plead for regarding this theory as anything but a myth (a very interesting one though). Biologically man is a specific development, not something radically different.
Of course we feel different, because we have created our own symbolical standards according to which we are different. "God created man in his image." The only thing we can be pretty sure about this sentence is that it was not written by a giraffe...
