The planet Kobol is the one of mythical planets in the Gallactica fictional universe. Kobol was home to 13 tribes of early humans. During a great catastrophe, they had to flee the planet. Twelve tribes travelled through an energy barrier and settled on a group of habitable planets in a common stellar system. While the 13th tribe, went further and settled on a planet called Earth. The premise of the show finds the remaining survivors of the 12 tribes searching for Earth, what many of them believe is just a myth.
In rereading this, it is difficult to tell which is science fiction and which is a religious belief. I find them both equally entertaining ... maybe not, maybe equally interesting. If Romney wins the election this November, I am sure we will have a good four years to learn more about Kolob.
