I think Darwin's theory, contrary to creationist lore, has given us a notion of our place in the world. Jesus told his disciples they are in this world but not of this world. Unfortunately for the literalists, we're both.
What's so horrifying to the creationists about sharing encyclopedia-length genetic script with every other living thing on this planet? Our origins in the biosphere are nothing to be ashamed of. The fact that life developed over billions of years to the point where we have the intelligence to decipher history's patterns simply staggers me. I know my sense of wonder is shared with everyone else here, except maybe Dan.
Maybe the real opposition to Darwin's theory comes through the specter of natural selection, the cruel creator. Science doesn't show us as the product of a purposeful developmental plan by a being with foresight and intelligence. It shows us as the late arrivals into a world where biological complexity and beautiful design come at the price of a mind-boggling amount of death, waste, extinction, competition and cruelty. Darwin made us realize that the great creator of all the wonders of nature is indeed God the Destroyer in the form of natural selection.
P.S. I still like this analogy to explain the correct way to look at the micro-macro debate: the creationist says that macroeveolution doesn't happen because only microeveolution has ever been observed.
By that logic, heat waves don't happen because you can't measure them with a thermometer. All we can empirically test, says the creationist, is a really hot day. Therefore a lot of really hot days in a row don't constitute a heat wave, just a lot of really hot days.

The dark nursery of evolution is very dark indeed.
