nostradamus predicted several different dates the world will end. One of them being january first 2150, because thats the day we will cros into the age of aquarius and out of the age of piscies. The bible even has scripts where jesus tells his disciples he will be with them until the end of the age. And at the beggining of the new age they should follow the man carrying a bucket of water, aquarius the water bearer. Its all based on mythology and the stars. Most religions are based on astrological sequences. The world could end long before or long after december 21st, 2012. The sign of the zodiac explains all of it
