People miss some very obvious things with the whole 2012 thing. They're all like "Oh, it's absurd, the world won't end." Here's the thing though. That date, December 21st 2012 that not only the Mayans, but also the Chinese had predicted, is ASTRONOMICALLY SIGNIFICANT. That just happens to be the exact day that our solar system comes into alignment with the center of the milky way galaxy, after which it will cross over into the other hemisphere of the galaxy and the planets poles will become reversed. Will anything happen? Probably not, but the point isn't that they were wrong... it's that THEY KNEW!
Doesn't anyone find it slightly odd that these supposedly non-technological ancient civilizations knew of astronomical events and the exact day on which it would occur THOUSANDS of years before we did?
Edit: Before you all go and say it's a coincidence that they picked that day, it only occurs once every 26,000 years or so. There's no coincidence here.
