The Mayan calendar didn't end in 2012 because they thought it was going to be the end of the world, the calendar ending there had practical reasons, for sakes of brevity, I'll leave you to google the rest. I'm also finding it amusing how we "trust" the "insights" of an ancient culture we somehow believe had the "power" to "foresee" the end of the world. Even if the Mayans believed that the world would end next year (which they did not), who cares, and why believe them, or even worry? I find it funny how people attribute so much "prophecy" to a peoples most don't know the first thing about.
