It is nonsense. It won't happen in 2012. It is only a narrative story that can be told to make a movie or an animation movie. Just look and see. Especially, we, the Islamic people deny that assumption.
Indeed, we have such belief that there will be the day after that the whole world will be destroyed totally, but Allah (the Almighty). But it won't happen so sooner like little people say. It will happen after the appearance of Dajjal (a very bad man ever, a cursed man ever, a man who have a huge power who will proclaim himself as a god because he can do what common people can not do); he will fight and kill all moslems all over the world and every body who runs against him; those ones who follow him will be in the hell and the ones who run against him will die in honour.
Dajjal will be given by Allah power to show off himself for 40 years; some years before that Al-Imam Mahdi will be sent to fight against him. At the forty years, Nabiyullah Isa 'Alaihissalam will be sent to kill him, and he will be dead. After that, Nabiyullah Isa 'Alaihissalam will rule the world for 40 years also. It is after this time the doomsday will happen.
It is the reason, why no Islamic People believe on the assumption of 2012 doomsday.
