Schools shouldn't teach neither evolution, nor creationism, nor any other origin story. Because it is something that doesn't matter at all – knowledge without value.

Worse is that the majority pupils around the world will be taught both the Abrahamic creation story, the origin of man according to evolution, and usually a third or even fourth creation story from local pre-Abrahamic mythology. In the same school and from the same teacher. Talk about confusion of the highest order!
