Thanks for that clarification. You are right in what the two are based on. But, regardless of what they are based on, I believe that since they are opposing, they should both be taught mainly for the reason that it does raise questions and promotes debates and that in itself would be good experience for students to learn from.
Theories are based on assumptions and probabilities. Personally, I believe in creationism, which is more logical to me. But, as Buddha said: "Believe nothing, no matter where you read it or who has said it, unless it agrees with your own reason and your own common sense."
