Initially I wanted to stay away from evolution in this blog, but I guess you have to bring it into dealing with religious nuts. This is a bit different from a pure anti-creationism blog post however. I read this article on National Geographic about some of the strange creatures that existed during the Cambrian explosion.
I find this story very enlightening with regards to science and acceptance of facts. If you look at some of these creatures, they look like something out of a science fiction movie, but besides the colours of these animals (maybe pink?) this is what they look like. Now scientists could ignore this and pretend they do not exist like what happens when you ask for proof for the existence of god. But they do not! They accept the fossils for what they are and try to understand them better.
This kind of approach to anything makes progress the goal! Understanding small things sometimes is necessary in understanding bigger issues. So why if god is so big, is there no strong science surrounding this entity.
