First off, evolution is NOT a belief/myth/theory. Evolution itself is fact. Evolution does occur. It can be observed in some cases. Mostly, it takes too long to manifest itself (longer than our lifetimes that is). The part that is a theory, is natural selection. Natural selection is the predominant (I'm not actually aware of another explanation) mechanism explaining evolution. Natural selection is not perfect, but it's the best explanation that they've figured so far.

I think it's kind've appalling that people even entertain the thought of 'teaching' intelligent design in schools. There is absolutely not a single shred of evidence or anything supporting that theory. Because that's exactly what it is, a theory. Just because something doesn't jive well with your beliefs doesn't mean you should ignore it. That is ignorance. You can't just decide you think that the sky isn't blue because it doesn't follow your beliefs. And you definately shouldn't try and force ingnorance on anyone else.
