I start off with a challenge. The recent trend in ID flapdoodle is to maintain -- vociferously -- that they aren't trying to put religion into classrooms. Very well. The challenge is, then, to demonstrate proof on an intelligence that could produce the myriad life-forms on this planet. If you can do it scientifically, I'll bow to you and be all for teaching ID in a science class.
Lets get something straight! Intelligent design is NOT about religion that's creationism. Since "when" is alien intervention considered religion? Secondly there is NOTHING stating they want to "teach" ID in the classroom! All they're talking about is "mentioning" it!
