One of the things that's always baffled me, and I say this completely honestly, is that if somebody looked at something like a Boeing 747, any high rise building, or well constructed, artistic looking bridge, and said "wow, evolution is amazing!" we would think them insane. But do that with something as intricate as a feather, or the brain (of any animal) and it's immediately acceptable.
Then there's the second law of thermodynamics, which seems to be ignored by evolution, where it seems to be accepted that entropy decreases over huge amounts of time.
