New theory? Not really.
Much later than a book that came out in 2000, but this is some sort of amazing new theory?
I've referred to this theoretical race in print many times as "Hidden Neighbors" and Subterrestrials (divergent evolutionary types, as opposed to other-dimensional Keelian ultraterrestrials).
I am glad to see this idea gaining more acceptance--including the manipulation and deception factor. But this idea of subterrestrials with an advanced civilization goes back even farther than Richard Shaver--It goes all the way back to Gilgamesh.
Recent writers and supporters of the non-paranormal, hidden race hypothesis have included Timothy Beckley, Brad Steiger, Richard Shaver, and several others.
My writings and radio interviews have stated that there are a)unknown (sub)terrestrial races that are subterranean in habitat, with advanced technology; b)unknown (sub)terrestrial races that use humanity as a genetic stock and for other uses, as well as prey on surface-world resources; c) unknown (sub)terrestrial species that explain many "cryptid" sightings and encounters; d) subterrestrial humanoids who use misdirection, technological illusions (cloaking and holography, among others) and so on to MISDIRECT our attention to a DECEPTION about "extraterrestrials"; and so on.
Nothing new here, but the idea appears to be spreading and catching on. Pretty soon it may even be "hip".
I do look forward to seeing Mac's thoughts on this topic.
