I think QuantumJG brings up a very good point: Why are humans so special? I think most people do not comprehend <just how large> the universe is. I can tell you that (to a rough estimate), the universe is 156 billion light-years wide. This is a truly unfathomable amount of space. We are just one species, on one tiny planet, in one galaxy, out of many.
We are nothing special.
We haven't been here very long (in fact, if you imagined a person holding their arms apart, and this length designating the age of the universe, human existence is a sliver of the person's fingernail.), and we won't be here very long either (species have an unsettling knack for becoming extinct quickly).
To assume that evolution holds for all species except homo sapiens is essentially arrogance. We are just another species. I accept the theory of evolution for all creatures, great and small. While the specifics may be heavily debated, I still accept that we evolved from something, which evolved from something else, which evolved from something else, ad infinitum.
