There is a movie out about the end of the world in the year 2012, or something like that, based on a prediction by the Mayans a long time ago.
It may be an entertaining movie, but there is a problem with this notion of a Mayan prophecy.
Some people say it will bring a new human consciousness (a good thing, I think). Some say it will be a magnetic pole shift (with disastrous results). Some say it will be a black hole event (with disastrous results). Some say it will be the approach of another planet (with disastrous results).
Clearly, disaster is winning the vote on what the prophecy is. Death and destruction is always popular with prophecy.
Now, why do you think there are so many views of what's going to happen? If there was a prophecy by the Mayans, why would there be all these theories? Can you figure it out? Do you think maybe there was no such Mayan prophecy? If so, you would be right. It's simply the end of the calendar they were using at the time. They made no predictions about what would happen, and there is no indication that the saw any significance in the approaching date. That's why there are so many variations on what is "going to happen" on December 21, 2012.
