"In 1982, NASA itself officially recognized the possibility of this legendary Planet-X, with an announcement that some sort of mystery object was really out there—far beyond the outermost planets. This NASA statement appears to confirm those ancient 6,000-year old Sumerian picto-graphic descriptions of our parent solar system containing at least one more planet the Sumerians called “Nibiru” —which means “Planet of the Crossing.” Since then, NASA has been rather quiet about X, which suggests that something quite mysterious may yet be out there lurking in our collective future. All the indicators are now in place to confirm X’s existence and only time will tell approaching (2009/2012), if the Sumerians/Mayans/Toltecs/Aztecs were indeed correct! "
