The Christian viewpoint on this is that the Anunnaki in fact were the Giants that walked the Earth, which the Bible is talking about. Those Giants were the nephilim, who rebelled towards God and were cast down to Earth from Heaven, together with their master, Satan. Christians explain the shape shifting theory by saying that the aliens in fact are demons and the nephilim. They mean that the persons that have been seen shape shifting are merely demon possessed due to their black magic practices, and sometimes the demons "bleed through" and show themselves, either in reptilian form or as the "grey aliens". Maybe the different conclusions are just different interpretations of the same thing? http://www.illuminati-news.com/moriah.htm
THE ERIDEANS AND THE ANUNNAKI http://ambilac-uk.tripod.com/cometlee2012/id5.htmlThe ET Deception: Knowing Who the Gods Are, and Who Are Not Gods by John Lash It is clear that the Sumerian Annunaki and the Gnostic Archons are identical to modern ETs.....According to the Gnostics, the "true gods" are the Aeons of the Pleroma. And one of these is Sophia, the wisdom goddess, who morphed into the planet earth. Today we call her Gaia. She is the ground of life and consciousness for the human species and all sentient life, including molecular life. Such is the ancient Pagan teaching preserved by the guardians of the Mysteries. Today we stand at the threshold of reviving and reliving that teaching. The trick is, to get past the extraterrestrial tricksters to the real magic of life on this earth.
