@Nikkoru To play the devil's advocate, although I have never been creationist or even religious myself, I'm still terrorized by the idea of my own mortality. Therefore I understand the someone would want to believe that they are immortal and the best way to maintain this belief is by hiding behind a curtain a mystery. By dissipating the mystery evolution is a threat for this comfortable delusion. It's perfectly understandable that they would want to waste so much effort to defend it.
Many religious people can accept evolution within their theology without much dissonance. Aside from that, it's not that I care what scientists believe personally, anymore than my lawyer or doctor beliefs affect my legal defense or medical care. It's the vehement acceptence and unwaving practice of the scientific method and logical inquiry which defines science. This means your ideology should not matter if you claim to be a scientist, and this faith based psuedo-science is utterly unacceptable.
While I can accept that people of faith want to defend their beliefs from becoming irrelevent. If they're reasonable and intelligent enough to comprehend the arguments for evolution sufficiently as to be able to subvert them, they would have the available faculties to recognize the inherent flaws in their position. So they're pursuing ends that they themselves, with any measure of introspection, should be capable of dismissing.
The fact that they do so speaks to a basic insecurity in their beliefs. Ironically though, it's not evolution itself which is threat to their position, but the culture of demysification and rational understanding of the universe that science represents which is the true enemy to their mindset. Ironic because, they themselves in trying to counter sicence with their own flawed science, are participating in said culture. Trying to prove faith just weakens it.
They could, with the minds they believe their god gave them, put them to a use which isn't futile.
