I think I can help you.

The man who began the study of the sumerian tablets, annunaki, planet x, nibiru, nefilim etc etc. who put it all out there is a man by Zecharia Sitchin. He wrote a series of books known as the Earth Chronicles. The different books are known as 1. The 12th Planet 2.The Stairway to Heaven 3. The Wars of Gods and Men 4. The Lost Realms 5. When Time Began 6. The Cosmic Code and 7. The End of Days.

Also, Zecharia's theories don't contradict the bible, but coincide with it. Contrary to what somebody else said. The theory is, to make a long story short: Annunaki travel in a planet they can control, planet x. they land on earth and create man to look like them. After a while they see man is corrupted so they destroy the whole earth in a flood, but one of the God's feels sympathy for man (the one who created man) and decideds to save the only righteous, Noah. and the story continues from there.

As for who the nobody is, you probably know as much as I do. It seems to me, the nobody is just some regular joe who found out the secret of enlightenment. Maybe he was sent by God, Maybe God saw him walk in his ways, whatever the case the Nobody is protected by him and now TPTB had to change their whole game plan to something else. Now im no authority on this, im just a regular dude...and im definately not infallible.
