Then I demand that the Great Green Arkleseizure theory also be given equal time. What about Last Thursdayism? How about Native American creationism? What will Thor and Odin think if they don't get equal time? If you have another competing SCIENTIFIC theory, then great, give it equal time in science class. If not, well then evolution is the only scientific theory there is.
Competing is the key word. I knew somebody would try to make the case you made, but that argument is invalid to me. Very few--if any--people believe theories other than a form of ID or Darwinism. Students should hear what the top scientists in the field are studying--that would be ID and Darwinism--not some garbage about aliens.
