Evolution

Something that leaves my head scratching -

I know a lot of people who believe in creationism and say that evolution is absolutely wrong. Yet, when asked, they really don't understand what evolution is. I'll bring up a specific point and they'll say, "You know, I don't really know the details..." or "I don't really understand what that part (of evolution) is."

One example is micro versus macro evolution. I'll talk about a general point on micro evolution, and they'll readily admit that they don't understand the specific points of evolution.

So how can people discredit a scientific theory that they don't even understand? That seems a bit close minded. I would never reject (or accept) a theory that I don't understand. "Oh I don't understand refraction, so I don't believe rainbows are created from the separation of light."
