I'll ignore the ever amusing "which member of the Palin household is actually pregnant" debate, and the even more fun "did McCain do ANY due diligence before choosing Palin?" debate since they're being covered extensively. The issue that's far more important is the Creationism debate.
From Wikipedia - The word mythology refers to a body of folklore/myths/legends that a particular culture believes to be true and that often use the supernatural to interpret natural events and to explain the nature of the universe and humanity. This is a clear description of Creationism, or the belief that a God created humanity and the Earth out of nothing.
In Norse mythology, Odin and his fellow gods created humans out of 2 tree trunks. In Greek mythology, humans were created out of clay by the gods. Yet no one actually teaches those two theories as science because they're clearly just as crazy as the idea that some single God created humanity out of nothing. The wikipedia definition of Science is: Science (from the Latin scientia, meaning "knowledge" or "to know") is the effort to discover, and increase human understanding of how the physical world works. It's not about taking ancient books and confusing them with actual facts.
However, GOP VP choice Sarah Palin actually believes that we should teach Christian mythology in the classroom, and I don't mean in the ancient literature class. In both a televised debate, as well as in interviews, Palin declined to answer on whether she believed in evolution, and then went on to say that creationism should be taught in school, ignoring the 1987 Supreme Court ruling banning the practice, as well as ignoring the concepts of intelligence and common sense.
It's frankly just pathetic for the top country in the world to be putting forth a major party candidate with such religious zealot views - is it any wonder the US continues to fall behind the rest of the world in Science knowledge? There is MYTHOLOGY which we learn in Literature class, and then there is SCIENCE which we learn in science class - and Sarah Palin doesn't understand the difference.
The good news is that there is a clear choice in November - vote for ignorance & mythology or vote for knowledge and science - hopefully the US will make the right call.
