Incorrect. They are called EB Ones and are from Zeta Riticuli and they are the ones that cultured DNA from already evolving primates to create humans, so far as we know, as a sociological experiment. EB Two are the smaller ones that are genetically engineers clones mad to interface with Humans.
Annunaki is a term created by the Sumerians for the worker class, the Dun Gir are the ones that lead. And even these phrases are misrepresentations from older stores before the Sumerians. Unfortunately Sumerians were only 6 thousand years ago, and they story they are telling is about 30 thousand or more years before them. It is surprising they retained even this much. The names the Sumerians often used (Enlil, Enki, Anu, Innana, etc...) are also incorrect and just their own interpretations of older individuals from antediluvian times. They were probably not aliens but humans of renown, as they say, who are charged to manege human stock. After all we were made to toil.
If this at all interest you I suggest Linda Moulton Howe, Richard Dolan, Paul Hellyer, Graham Hancock and maybe Steve Greer and Zecharia Sitchin. Stay away from David Icke, Tom Delonge and Erich von Däniken I think their misinformers, there are many. EDIT: Oh and Giorgio A. Tsoukalos is a TOTAL fraud. He is the biggest misinformer, he was there to create illegitimacy to this whole sphere of knowledge.
Good luck!
