OK...circular argument. Brilliant. My faith tells me that an all-powerful God created man and woman in a special act of creation. The Bible also tells me that both man and woman "fell," that sin entered the world, and that mankind has suffered ever since. I think the existence of a sin nature in man is pretty observable, providing pretty solid proof that the account of Genesis is accurate.
Consider the topic of this thread -- that evolution is consistent with Christianity and with conservative philosophy. As a Christian (I assume you're not one), and as a conservative, I can assure you that the premise of the article is false.
