Why the Sun Really Shines, Really This Time (We Know for Sure)

Question 1: Should we teach religions in school in the same manner that we teach science?

The answer to this question, I think, depends very highly on how schools teach science. In a very non-ideal setting science teachers teach scientific theories as though they are the only theories. In those same non-ideal situations science teachers teach science as though science is always 100% correct. Some science teachers in the sixties taught for a fact that the sun a sphere of gas. They used this song as a teaching aid:

This is a more fun cover version: 

Later, science advanced and scientists determined that the sun was not a mass of incandescent gas, but was rather a miasma of incandescent plasma. For fun here's another video:

Anyhow, back to serious philosophy. The point is that honest science teachers should teach science as it is: a tested hypothesis, which given the current data and observation, is the best explanation for the empirical facts. Religion, while based on faith rather than reason and direct observation, offers another explanation. 

I think that in honest academic settings it would be appropriate to teach science as an empirically observational based explanation of facts, and to offer a general religious studies courses as an option. It would be discriminatory and unfair to teach only one religion and it would largely impractical to teach all of the religions. So, perhaps it would be best to, beyond offering a few religious studies courses, provide resources through which students can learn more about various religions.

I'm not sure how practical that is, and I'm not sure where to draw the line.
