Let me make this simple for you.
The "nobody" and the "he" are hoaxes created by delusional people. The "nobody" thread was posted by an attention seeker with no honest insight into the "illuminati" at all. The "he" business is also a hoax and is about the megalomania of some of the posters here.
Take a good look around, you'll find something interesting. There are more SAVIORS and CHOSEN ONES on this forum than the rest of the internet combined.
For whatever reason, this forum gathers them up like flotsam. You have the guy who "fights demons" every day on the "astral" and is THE supreme warrior for the christian god. You have the "christ michael" dude. Lest we forget the Supreme Queen. The guy who used to be just a bit nutty and was "part annunaki, look at all my tv appearances" who is now the next jesus. You have... well. The list of "saviors" on this forum could take up a page all by itself.
These "nobody" and "he" things are all part of the "I'm the extra special chosen exalted world saving one! No, really! Look at me, look at me!"
Now, the Annunaki? Another story altogether. That is more complex and ancient, and there could--I stress COULD--be more to it than to the other silliness you're talking about.
Most of the silliness on these threads are people trying to pretend to be "in the know" and special. They say stupid shit to indirectly "brag" about how they know [a whole bunch of shit they don't know]. They feed off of the other guys who are trying to pretend they're all "in the know" and have exalted special knowledge, too.
Don't be sucked in. It's stupid posturing and megalomania.
