"The observation, identification, description, experimental investigation, and theoretical explanation of phenomena."
Creationists and ID are doing all that with the theory. They observed it, identified it as an act of a being, described it, are currently experimenting in it, and have a theoretical explanation for it. I think that's science. But anyway, I'm not advocating teaching creation or even ID.
It isn't much to ask for. Just tell kids that there's another theory, evolution isn't proven fact, and briefly tell them the basics. I hope no one believes that evolution is a proven fact like gravity. It hasn't been tested or thoroughly proven. Creationism is a new field of study that's scrambling to establish itself. Even if just for political knowledge it would be a good thing for them to know what people are saying. This is becoming reminiscient of the Scopes trial.
