If you think he is wrong, give us a sense of why creation science is a science. In his essay Kithcer most certainly argues against creationism being a science. Clearly, creationism violates these standards. What I'll focus on is the unifiction aspect of Kithcher's criterion.
Creationism offers plenty of explanations.
Man was created in six days by God. Women were created out of man for companions. Animals, water, and plantlife were created for us to live on. This and much more make up the creationist's view of our history. The problem comes in when we try to unify these beliefs with another theory.
