Myths

A lot of people out there probably wonder why so many myths are taught in school while A) nobody believes them anymore and B) they have no clear purpose in today's world. To quote Rick Riordan "It's not like on our job aplication it's going to say please explain why Kronos ate his children. (This may be a word or two off from the actul text, but you get the idea).
I enjoy reading Greek myths, but that still doesn't explain why they have to be taught in schools. That is, until, you realize what a profound effect they have on culture.
For one thing you can tell ceratin aspects of things named after them (For example, I knew Io was a moon of Jupiter simply by knowing Io was a moon and the Myth of Io), but they have other effects too. Traditions, even now, are based off of them. In Cross Country it is considered a minor form of heresy not to walk slowly over a bridge, based off the Eyptian myth that when you are over running water you are free from gods. The eagle was the symbol of Zeus far before the united states even existed. So yeah, the gods have a profound effect on culture today.
