How about the fact that there's no scientific evidence in favor of ID, and the subject being taught is science? If there were such evidence, then that would translate into positive scientific evidence for the existence of God, and that doesn't exist. Just like there's no scientific evidence of the existence of Allah, or Zeus, or Thor, or ghosts. Sure, Jesus existed, but so did Mohamed. That a person existed doesn't validate all the stories told about them. There are lots of whoppers told about people who existed in History.
It was the scientist saying it, not me, and I think he proves his point by your subsequent posts on clouds and men from mars.
