You like that picture, huh? Is he related to you or something?
Yes, when teaching science, teach science. You can explain, if you want, other scientific theories that were disproven if you want. Explain that nothing is concrete. But teach science.
If you're going to teach religion, ok. But don't call it science. Explain that there are people who don't believe in this scientific theory if you want. But don't teach that there's just as much validity, based on evidence, in creationism. That's all.
