The Mayan Prophecy?

Is the world really coming to an end in 2012? Or are we seeing another hoax? Who were the Mayans? Can their prophecy be trusted, or is it been misinterpreted by end of the world freak. Was the Mayans even spiritual talk-less of been religious. These are some of the questions that needs to be answered. From my knowledge and research, the Mayans were highly developed society that engaged in human sacrifices. They also practice astrology and were able to predict the future. Was their way of life responsible for their demise and destruction thousands of years ago. Time will tell!
