It's one way to introduce a subject. Personally, I don't think it's a very good way. Often, it just creates and knocks down straw men. For example, most of the people who are accused of thinking the earth was flat really didn't think that.
But is it really what you want? "Well, there's an alternative theory, in the Bible, but the Bible is full of scientific errors, and it's completely wrong about the age of the earth and the origin of life".
I'm agnostic. I am not prepared to accept our existence as being accidental anymore than I accept the idea of creation by a higher being. That being the case, if the class topic is "how did we get here?", I can't possibly favor one theory and dismiss the other from discussion.
I can't go to church for any scientific consideration of creation. At the church I am expected to have faith and follow the instruction of that particular church based on that faith. The place to consider creationism is in science class and then, if you subscribe to the notion of a higher being creating everything you might want to subscribe to one of the various religions.
