The documented roster: Berossus's Oannes, daily from the Persian Gulf; the Dogon Nommo, amphibious instructors from the sky who come down in an ark, this archive's Dogon file holding the Sirius controversy; Viracocha, emerging from Lake Titicaca to create and teach; Quetzalcoatl, the feathered serpent credited with calendar, writing, and maize, departing eastward over the sea; Osiris, in Plutarch's account, traveling the world teaching agriculture and law; Manu and Matsya in the Indian file; Fu Xi and the sage-kings in the Chinese. The pattern's constants: arrival, instruction in the civilized arts, departure, and the promise or possibility of return, with flood adjacency in most versions. Plato's own version is documented in the Statesman and Laws, the age of the gods' direct shepherding, and the Egyptian priests' claim to Solon that the Greeks were perpetual children, their records erased by periodic catastrophe.
The alternative shelf's synthesis, the documentary's own: the teachers were real, survivors or missionaries of a drowned seafaring culture, the flood myths being their homeland's obituary, the fish iconography being maritime kit, the departure being the return voyage or the last boat, and the pattern's consistency being evidence of one source culture rather than independent invention. The shelf's strongest documented card remains the same as the history gap's: the ice-age coastlines, where a seafaring civilization would have lived, are under 120 meters of water, so the absence of the teachers' home port is exactly what the thesis predicts, an argument the archive files as unfalsifiable in its current form, which is not the same as false.
The claim: the teacher-god is every civilization's explanation of itself to itself, the awkward fact that a people has laws, crops, and letters demanding an author, and the stranger-from-the-water being the author's safest costume, foreign enough to explain the novelty, departed enough to excuse the maintenance, so that the pattern documents not a visitor but a universal bookkeeping problem: how do you account for what your ancestors knew, when they are not here to ask. Verdict: the archive's verdict holds both shelves without merging them: the genre reading explains the pattern's uniformity, the survivors reading explains its content, and the deciding evidence, a port, a wreck, a genome, has not surfaced, which is the wing's standing finding. The teachers all left by water. The record all lies under water. The archive's readers know the protocol by now: cite the roster, fund the sonar, distrust the exact match, and note the one constant no tier disputes, every culture remembered being taught. Nobody remembers teaching themselves. That, in the archive's long experience, is either the oldest memory in the file or the oldest humility. Both are worth keeping.
If the teacher-god story is universal, is it a shared memory of one event, a shared need producing one story, or a shared author, and how would the record tell those apart?
