The authors claim that they found a star gate in Cairo (suspiciously close to where the movie Stargate placed its own portal) and met with an extraterrestrial being, who confirmed for them the history of the civilization of the Pleiades.
Anyhow, whether you accept the book’s premise depends on how much you trust that they have special access to interdimensional aliens.
But in promoting the book, one of the authors, Bruce Fenton, who is not the economist and frequent CNBC guest of the same name, so far as I know, made a bizarre claim that I think does a good job of illustrating how alternative writers build castles in the air by piling claim upon claim:
Though the core thesis is of course on the matter of beings from the Pleiades being key players in engineering Homo sapiens sapiens, my own favourite part was my work on the hypothesis that the Pleiadian-human hybrids of Palenque had extremely high levels of endogenous DMT in their blood, hence their blood being considered a sacred offering and a key to other spiritual dimensions of existence. As far as I know such an idea has never before been explored or even contemplated as the explanation for why Mayan Lords (many of whom being such hybrids) were the only ones that had blood considered suitable for rituals.
I suppose I should be more focussed on the core subject matter but that was where I got most excited as it helped explain a great deal of weirdness in my own life.
Fenton seems to have decided that such explanations are not good enough; instead, his own life experiences can now be attributed to alien blood, a personal connection to the aliens who are substitute gods. Indeed, Fenton describes Ancient Aliens in Australia as dealing with mind-blowing “metaphysical” and “cosmic” truths, again reinforcing the relationship between ancient alien beliefs and a desire to create a physical basis for the divine.
Notice that Fenton chooses Palenque as the site of his alien landing—the same place that Erich von Däniken found his “rocket” carving on Pacal’s coffin lid. This is no coincidence. The idea that the Maya kings were alien hybrids is an old one; Alan Landsburg was the first to suggest it in his Outer Space Connection (1975) movie (narrated by Rod Serling) and its companion book. There, Landsburg proposed that the Maya were a colony of hybrid aliens (though primarily at Uxmal rather than Palenque) and that they misunderstood the idea of cryogenic freezing as a form of immortality and therefore set the date of 2011 (later revised to 2012) as the time that the frozen aliens would thaw out and return.
Fenton and his coauthors have simply adopted old 1970s ideas, added some of Graham Hancock’s drug-fueled “mysteries,” and moved the whole thing to Australia as a new twist on Zecharia Sitchin and his Anunnaki.
Old ideas never die. They just get recycled and resold.
