just saying that the world will end on that date doesnt do anything but take any scrap of possible credibility that they might have had.
there's been a few movies of it already that have different reasons, volcanoes, aliens, etc.
but one of the main reasons for that date is the fact that that will be the winter equinox and it just so happens that the earth will be perfectly aligned with the center of the galaxy (which happens every 26,500 years or so), and is supposed to end the "4th" age and begin the 5th age.
then there's the planet Nibiru that is hurtling towards Earth's orbit this very minute... and a few other theories out there
then there's my personal one....
