Why is it said we are all to die in 2012?

Yours is not the only question regarding year 2012. There are so many predictions previously and all turns up to be untrue. Didn't the bible says no one knows the end of the world or the coming of judgement day. The coming of the end will be earthquake everywhere, wars against countries, fights among family, people disappear for no reasons, there will be false prophets and miracles. Do not believe. The coming of Jesus or end of this world is like a thief. You do not know when it happen. Since you are a Catholic you should hold on to your fate.
