I found this on another board and while reading post of the article it reminded me of what I'd read about the alleged planet Nibiru.
The one mentioned in Sumerian texts translated by Zecharia Sitchin. It's the home of the Anunnaki (translated as "Those who from the Heavens to Earth came")
I'm not saying it's definately Nibiru but it's interesting that it at least partly fits the stories. Perhaps some were miswritten or mistranslated.
There's the possibility it's not from the Solar System but another star system.
