Petricevic notes that the British royal family have Rh-negative blood and therefore are likely to be part of an intergalactic conspiracy. This is all standard ancient astronaut material, and Petricevic never bothers to do more that feint toward any reason to suspect that a particular blood protein would be associated with both slavery and absolute power, or why those two concepts would be the same thing.
However, as it turns out, a Sitchin-inspired writer named Betty Rhodes explained this much better than Petricevic in her self-published 2006 book Keeper of the Celtic Secrets. This book is presented as a novel, but like the quasi-fiction of Kathleen McGowan Coppens or the Shaver Mystery, Rhodes tells her readers that her novel might really be true beneath its “heart-wrenching love story.” It is also unsurprisingly racist, in which divine aliens create white people as the master race, a claim she attributes to ancient “St. John family journals” from Ireland written by a certain Job St. John around 1650 that reveal the following:
1) Caucasoid, or the WHITE races, descend from the Anunnaki, including the Elohiym godhead. And yes, the ancient Israelites, are actually descendants of the Elohiym royal family.
2) African or Negroid, the BLACK races, descend from the evolved Homosapiens and the hybrid created Adams; they are the EVES.
3) Asiatic or Mongoloid, the so-called YELLOW skinned people, descend from the Nefilim, the ousted royal party from Hibiru—notice I say Hibiru NOT Nibiru—Hibiru/Hebrew—are you still with me here? The Nefilim ‘giants’ were the reigning godhead until the Elohiym family ousted them, casting them to the Earth;
4) Indigenous or Native peoples of the land, the BROWN or RED races, descend from the evolved Homo sapiens and the Anunnaki—some not authorized by the Elohiym, but boys will be boys, and they made a good working stock of slaves. These people were the ADAMS.
What can you expect, though? She is merely echoing Erich von Däniken’s explicit claim in Signs of the Gods that the “black” race was a “failure,” and marrying that to Zecharia Sitchin’s adoption of the (genuine) Mesopotamian myth that humans were created as servants for the gods—a myth meant to explain the origins of labor, just like the Hebraic myth that Adam’s sin led to him being condemned to labor for his sustenance. To this, she adds more than a little Victorian-era scientific racism.
But Rhodes didn’t invent the Rh-negative claim; she merely made it explicitly racist. The claim already appears in David Icke’s The Biggest Secret (1999), in which he identified the Anunnaki not as cosmic Aryans but as cannibalistic crypto-Jewish Reptilians, and he suggested that Rh-negative blood was a sign of Reptilian (read: Jewish) ancestry. These Reptilians, who control world governments and manipulate global finance out of a lust for money, “certainly feed off human blood and flesh,” presumably in their Passover matzo balls, as in the old blood libel Icke draws upon but never quite makes explicit.
Icke’s views carried over to anti-Semitic literature, where the undated, anonymous book called The Truth about Freemasons, Illuminati, and New World Order connects Rh-negative blood to a global Jewish elite trying to destroy the world through Zionism. The book says that Rh-negative “blue bloods” came from the Caucasus mountains, and the authors mistakenly think that aristocrats literally turn blue at birth due to their Rh-negative blood, whereas the phrase refers to the blue veins visible through the skin of really pale white people, who in Spain were the aristocratic elite, unmixed with darker Moors. The phrase comes from the Spanish sangre azul.
So, while Petricevic presents the “new” idea that Rh-negative blood might be associated aliens as some kind of entertaining lark, in reality it’s more often been used as a kind of dog-whistle calling to racists and anti-Semites under the cover of “harmless” extraterrestrial speculation. At any rate, the idea is not new and to present it as such is false advertising. But what can we expect from ad-choke fringe history clickbait?
Update: As I learned this morning, the “news” value in the story apparently refers to Nick Redfern, who has a new book out about the Rh-factor called Bloodline of the Gods, published last week, in which he recycles the above material to hunt for alien ancestors.
