Foxfyre, if you really look at this, anybody that wants to address how the earth came about must admit, we don't know, period. Yes, there are scientific theories, but when you deal with the subject of how we got here, it seems to me that religioius beliefs are impacted in some way, because it touches on the very core of our life philosophy and belief. To teach a scientific theory, to the exclusion of a possible creator, is essentally teaching something that few people actually believe. It seems far more logical to me that a creator should at least be mentioned as a factor in how all of us got here, not as a fact, but as a possibility. After all, scientific theories are not facts either, they are theories. And one does not have to exist to the exclusion of the other, and this should also be taught.
There should be nothing scary about this concept, after all, most cultures have religious beliefs that include a creator or God, or Gods, that influence the creation and how we got here. Teaching this does not require teaching any certain religion, but it could include some discussion of how different religions treat the subject, not in great depth because that should be for religious classes in college. But the subject should not be ignored, and that is I think the only point that Palin made.
