There's increasing evidence that the human tendency to see 'design' or 'purpose' in biological entities is hard-wired into our cognition, probably by evolution. Dennett calls it the 'design stance'. Your incapacity for getting beyond this cognitive hardwiring, ironically, is a sign you haven't been able to transcend what evolution has equipped you with, as a rule-of-thumb for hunting or escaping wild beasts.
Of course, expecting as much out of someone who still believes 3000 year old creation myths is probably unreasonable.
