Basically, the comet that many crazies thought would fullfill the irrational logic behind the Mayan Civilizations calendar won't be close to us or even large enough to do anything if it were.

Who said it had to be a comet, Might be a solar flare or aliens might kill us. Maybe something goes wrong at the earths core so it explodes

or it might be nothing at all.

Or perhaps it is me that intends to destroy you all.

Well that would probably be more realistic.

The mayans never predicted that the world is going to end...
For them this is the third time (i'm not sure, it may be fouth or fifth time) the world is going to end. But for them the meaning of that is "the world as we know it". After this, according to them, the calendar resets., and "a new era begin".
So, what the mayans really sayd was that in 2012 there was going to be a radical change, and the world is going to be different (this can be political, economical, a natural disaster, everything).

How bout we all wait till we wake up on 01/01/2013 before we celebrate

So what? It's never been about a comet.

Gabe Newell's fart is more likely to destroy us all.

It will suddenly turn and head straight towards Earth.

there are so many other ways we could die horrible painful deaths that i dont know why youre getting worked up over us not dying to this particular comet.
