Why is there resistance to evolution?

Spiegel interviews Dan Dennett who has some thoughts on the subject. The whole interview is worthwhile, but see excerpt below.

SPIEGEL: In the center of the debate is the theory of evolution. Why is it that evolution seems to produce much more opposition than any other scientific theory such as the Big Bang or quantum mechanics?

Dennett: I think it is because evolution goes right to the heart of the most troubling discovery in science of the last few hundred years. It counters one of the oldest ideas we have, maybe older even than our species.

SPIEGEL: Which is what exactly?

Dennett: It's the idea that it takes a big fancy smart thing to make a lesser thing. I call that the trickle-down theory of creation. You'll never see a spear making a spear maker. You'll never see a horse shoe making a blacksmith. You'll never see a pot making a potter. It is always the other way around and this is so obvious that it just seems to stand to reason.
