What if the ancients knew something we don't?
We know they did not, because they were nothing more than stupid, poorly developed versions of us. By definition, they were wrong about everything. Our new ways of thinking have proven themselves superior, and elevated us from the dark times caused by the ancients. New modes of structuring our thoughts and interactions are better, and these new things have saved us from the futility of the past. The very few good things the ancients accomplished were the things that turned out to be the undeveloped component parts of the ways we do things now.
Sometimes, though, when my monitor isn't looking, I start to wonder. What if they knew something we don't? Did anything happen during all those years other than a gradual progression toward the closer-to-perfection that is us? So many thousands of years. Just, what if?
