apocalypse - how badly real is that?

The reports from the web all makes it sound like myth or being someone's pranks. Books on this topic is so much words that it will put readers off from the first few pages. But video is different. I just watched the documentary from History Channel on doomsday on the year 2012. They have explained that the Mayan calendar which is so much more accurate into dates into the future have an ending. And the chinese I-Ching too have an end. While nothing much was explain on the I-Ching, they have more details on the Mayan calendar. It could predicts happenings in the future, which they manage to foresee invasion, war and disaster. While usually predictions are being gibberish, people have to sort out what they are trying to say, for the doomsday prediction, nothing much was mention. Either the documentary tries to put too much content into the scene or they have not decode it yet. Then one will have to think, whatever the cause, it will unlikely be what happened that killed the dinosaurs. If the dates stop, it would mean the land is gone or that Earth for some reason doesn't rotates anymore. If there would be a disaster such as flood or earthquakes that kills off all land-mass, the date should still move as the Earth continues to rotates while life are dying. So it is for the readers to decide, if such an ending would truly comes when mankind is not yet advance to escape into space. If time do stops on 2012, time on the rest of space continues. It would just be another star system's evolution and it is nature's doing.
