I totally understand creationist in the broad sense of the term. First Cause is not something that has been discovered and probably will never be discovered. Even believing that God created specifically the Earth for inhabitation, I completely understand. Denying that evolution occured in the face of so much evidence, I really cannot understand at all. I think that's where the willful ignorance comes into play, all the scientists who supposedly don't believe in evolution if you ask them they will state that they all agree with common descent. They are usually disagreeing with Darwin's theory that evolution happened slow and gradually, since there is much evidence to show that it can occur quickly. Specifically the evidence of speciation, there are observed evidences of speciation which took less than a decade.
