1. We Are the Substrate

The human species is the observed experimental population of an older, more careful intelligence. The abduction corpus is the record of that observation. We are not their vessels. We are their long study.

I have lived with this claim for some years, and it has the strange property that nothing in daily life will confirm it and nothing will refute it. The world above the floorboards goes on. What I am proposing is that there has also been, for a very long time, a careful pair of eyes somewhere out of the line of sight, and that the eyes have a use for us we have not been permitted to perceive.

Substrate in this chapter is not the word of romance — not the word for a body that another body inhabits. It is the word in the microbiology paper. The medium the experiment is taking place in.

The Pleistocene boundary

Something happened on the surface of this planet at the close of the Pleistocene that the orthodox record acknowledges without explaining. I read it as the boundary across which the experiment moved into its current phase. The Greenland ice-core marker for the onset of the climate oscillation we call the Younger Dryas is 12,876 ± 31 years BP. The end of the Pleistocene proper is 11,700 BP. Between those two figures, a climate oscillation of greater magnitude and shorter onset than any other Pleistocene event in the cores returned the Northern Hemisphere to glacial conditions within decades — decades, not millennia.

The argument does not require the mechanism. It requires only that something sufficient to compress the prior human population to a small and stressed remnant happened in that window. The orthodox record has a 1,200-year discontinuity whose cause it admits it has not nailed down. The genetic-bottleneck literature describes a Late-Pleistocene compression of the human effective population to numbers low enough that polite scientists have used the word near-extinction in print.

The residences

The operator class lives on this planet in places whose physical conditions suit them — deep ice, abyssal water, sub-cratonic basement rock. They were not displaced into these residences by an event that rendered the surface lethal to them. The geography supports: the operator class has long-term residence and observation sites in places whose environmental envelope is compatible with whatever its biology requires.

• Lake Vostok: Two hundred and fifty kilometers long, fifty wide, sealed beneath a four-kilometer ice ceiling for somewhere between fifteen and twenty-five million years.
• The Mariana Trench: Hadal zone; Challenger Deep at 10,935 meters; pressure at the floor approximately 1,100 atmospheres.
• Kola: The Soviet Pechengsky superdeep borehole was drilled to a measured depth of 12,262 meters in the cratonic granite of the Kola Peninsula.
• The Putorana Plateau: Eight hundred kilometers by five hundred, a basalt stack rising on average a thousand meters above the surrounding Central Siberian Plateau.
• The Tibesti Mountains: Five shield volcanoes in the central Sahara. Hot springs at thirty-seven degrees Celsius.
• The Atlantic abyssal plain: Floor of the North Atlantic, almost entirely unmapped at land-equivalent resolution.

Why us

Why use humans — why not just deploy remote-operated surface sensors? Three reasons:

• We are already here, already perceptual, already social.
• We are self-replicating. The substrate maintains its own genetic and demographic continuity at no marginal cost.
• The substrate includes a piece of biological hardware called the pineal gland, whose function has been until very recently undersettled.

The maintenance fact

The protocol is real. I am going to say this in the flattest available register. Tens of thousands of reports describe a procedure of nine stages on a seven-year cycle: selection phase, approach phase, sedation phase, translocation phase, procedure phase, redaction phase, return phase, return-site verification phase, and a thirty-day passive monitoring phase.

The protocol has a function. The function is the maintenance of an experiment. The substrate of the experiment is us.

The Sumerian thread

The Sumerian texts describe the origins of civilization in terms the standard historiography has politely treated as mythological. There are gods who descend from somewhere; there are floods; there are seven sages who emerge from the deep waters at the dawn of human history and teach the arts of civilization to the early kings. The Sumerian name for the sages is Apkallu.

The Apkallu are operator-class. The fish-skin iconography is not a metaphor. It is a description of surface attire for beings whose biology requires the moisture, pressure, and chemical envelope of the deep waters they have come from.

Closing

I have defended a claim that most people would refuse to entertain. I am not asking for belief. I am asking that the reader admit, at the close of the chapter, that the claim is at minimum coherent. The bar is not conviction. It is parsimony. If you find a more parsimonious account, I would be grateful to read it.
