What did the Mayans know, and when did they know it?

As the year 2012 approaches, more people are focusing on the ancient Mayan Calendar, since it predicts the end of the current age. This prediction coincides with other cataclysmic prophecies that have been around for a long time, so the fact that the world is potentially facing some serious upheaval cannot be ignored.

It's interesting reading, and for believers, it's comforting to know that the God who created the Mayans, and who gave them the ability to create their amazing calendar, is still in control, and His Will will be done regardless of mankind's predictions of what man thinks will happen. In that thought there is great comfort.
