December 21st marks the countdown to what ancient prophecies term “the end of time”， which many interpret to mean the end of the world - or at least， the end of the world as we know it. While there is much speculation and predictions regarding the events that will actually transpire， the impending end of the Mayan Calendar is building a momentum among the masses similar to the dreaded anticipation that we witnessed as the world approached the milestone year 2000 (remember Y2K?)。
The current economic chaos and global meltdown may be precursors to the transition leading up to December 21， 2012， the day that the 5，125 year-old Mayan calendar suddenly comes to an end， resetting to 0.0.0.0. But what will be the catalyst? Some believe we will experience a polar shift， as has happened on Earth before. Others predict the impact of a great meteor or asteroid， which has also catastrophically occurred before.
Or could it be the result of increasing global warming， or the reduction of the earth‘s magnetic field (which has already begun)， or the extinction of too many species， or could it be global Armageddon brought on by man’s incessant greed triggering war and destruction? Whatever the cause， in the three years leading up to this imminent global endtime， there must be some hope. Is it possible that ancient civilizations may have left us clues for our survival?
