There is a theory that the Biblical flood (or the Deluge)was cause went a passing planet came to close to Earth and a large section of Antarctica slipped in to the ocean. The ice rests on a gelatinous layer that is formed by the friction of ice/water and earth. The scary thing is that the planet (Planet X, Eris, Nibiru) is already on its way back towards Earth and is due to be at it's closest in 2012. Some say it is already visible in the southern hemisphere if you take a picture of the sun you can see it.
