Some scientists think your "evidence" has (purposely?) been misinterpreted. If you want to believe whales used to walk the earth, that's your right. If I side with the scientists who disagree, that's my right. Students should hear both sides.
There is no serious debate in the scientific community. The fact that a fraction of one percent of all scientists put their religious beliefs before their job doesn't change the fact that the debate has been settled in any meaningful sense of the word.
Students should only hear the sides for which there is evidence. This is a science class, after all. Science requires evidence.
Once ID has some actual hard evidence to back it up, then we can talk. But I won't hold my breath. It's been a couple thousand years, and still nobody's been able to find any.
