Creationists don't care about actually discovering anything via science. ID gives them the license they feel they need to ignore biological facts that disagree with the object of their worship, the Bible. They don't worship God or care about studying His creation. If they did, they would respect evolution as a great achievement of God, as Catholics have done. Instead, they worship a book.
"Instead, they worship a book."
That, actually, is not too far from the truth. We worship the WORD, not a book, to be clear...
