How to argue with an Evangelical?

[Cory]

Honestly, it really does come down to final authorities.  The creationist position ultimately boils down to this:  the Bible is the word of God, and all evidence must be interpreted in light of scripture.  In this respect, the origins debate becomes a war of world-views. 

But isn't that anti-scientific in the sense that it poisons the well? Going into something with a massive baseless assumption already taken for granted doesn't seem wise.

Creationists and Theistic Evolutionists don't view the whole "The Bible is True!" assumption as baseless.

I know but.... but.... it kinda is.
