Do you believe end of the world of 2012?

Are there any threats to the Earth in 2012? Many Internet websites say the world will end in December 2012.
Nothing bad will happen to the Earth in 2012. Our planet has been getting along just fine for more than 4 billion years and credible scientists worldwide know of no threat associated with 2012.

What is the origin of the prediction that the world will end in 2012?
The story started with claims that Nibiru, a supposed planet discovered by the Sumerians, is headed toward Earth. This catastrophe was initially predicted for May 2003, but when nothing happened the doomsday date was moved forward to December 2012. Then these two fables were linked to the end of one of the cycles in the ancient Mayan calendar at the winter solstice in 2012 -- hence the predicted doomsday date of December 21, 2012.

How do NASA scientists feel about claims of pending doomsday?
For any claims of disaster or dramatic changes in 2012, where is the science? Where is the evidence? There is none, and for all the fictional assertions, whether they are made in books, movies, documentaries or over the Internet, we cannot change that simple fact. There is no credible evidence for any of the assertions made in support of unusual events taking place in December 2012.

For my thinking, if you believe then it will exist, but if you don't believe it will not exist.
