According to translations of the Sumerian texts by Zecharia Sitchin, author of The 12th Planet, a massive object orbits our sun once every 3600 years. Called Nibiru by the ancients, its catastrophic flybys have driven the evolution of humankind. If the Mayan 2012 calendar prophecy is right, it could return within the next decade.
Do wisdom texts of other ancient civilizations also mention this object? Yes, and they are contained in The Kolbrin Bible. The Egyptians called it the Destroyer. The Celts called it the Frightener. Like the Sumerians, they also prophesy its imminent return.
If the Destroyer does return, would it end life as we know it? That depends on how it interacts with our sun. Consider this: between now and 2008, the space agencies of Japan, America and Europe will launch a new fleet of 5 new solar observatories into space. Curious? Listen to this podcast to learn more.
