I think that some of you need to research ID before you comment on it. You are assuming that ID contradicts or refutes Darwin's Theory of Evolution. All ID says is that God started everything and moves the evolution process along.
What would actually be funny is that if creationism is taught in schools, there are thousands of theories of creationism for Christianity alone. Some "refute" Darwin's theory, others accept all science. I think if it were allowed to be taught, you'd have the religious community cannabilizing itself in an attempt to get their theories into the books.
Ah, finally! On topic again.
So, God moves the process of evolution along. That's all fine and dandy, but in two spare afternoons of reading what ID actually has to say, I haven't read but the haziest conception of how and why this intelligent agency accomplishes this.
So there you are, standing in front of a class of eager high school children, explaining: "Well children, the theory of Intelligent Design states that it is possible to empirically discern "designedness".
You can establish the designedness of something if you can't think of any way it came into existence that is not ludicrously improbable. However if someone else comes up with a way you hadn't thought of that isn't ludicrously improbable, you are free to ignore them, because what they're telling you is just a theory, and has "gaps for which there is no evidence".
Designed things, as you know, are of course designed by some intelligent actor and subsequently built sometimes.
Well, that's that. Next week it's botany children".
ETA: In case I didn't get my point across: 'Gap' is the magic word here. As far as I can tell ID is replacing the gaps by an abyss.
