Guys I figured it out. The end of the world already happened in the real 2012, but some really smart scientists managed to make a simulation of the world and started it up at the point in history when the world formed. This simulation has continued to this point in time undisturbed.
The Maya 'predicted' the end coming in 2012 because they somehow discovered the 'blueprints' of this simulation, which is also why they knew how to map all of the paths of the stars and the planets.
/crazy talk
Let's all wait for the excuses of why the world didn't end yesterday.
