@Jegsimmons, actually, most civilizations tend to move both forward and backward in terms of technology, quality of life, etc. Europe went through the dark ages after the fall of Rome. Incan and Aztec ruins are all over South America, Pakistan and Afganistan used to be the center of culture and learning in the world and China has moved forward and backward so many times on this scale its ridiculous. To believe that society generally only moves forward is, well, ignorant of all of history.
