Episode 1124: Robert Schoch | The Brogan Report

Why This Episode Is Problematic

Joe Rogan hosts Boston University associate professor Robert Schoch for nearly three hours of fringe archaeology claims — most notably that the Great Sphinx was built before 9700 BCE by an unknown advanced civilization wiped out by a “solar outburst.” Rogan calls it “one of my favorite podcasts to date” and offers virtually no pushback.

TL;DR: A credentialed geologist promotes pseudoarchaeological claims rejected by the entire mainstream Egyptology and geology communities, while Rogan enthusiastically platforms them as a “mind blower” without inviting any expert rebuttal.

Who Is Robert Schoch?

Associate professor of Natural Sciences at Boston University’s College of General Studies (a non-tenured position in a general education unit, not a department of geology, archaeology, or Egyptology).
Holds a PhD in geology and geophysics from Yale.
Best known as the geologist behind the Sphinx water erosion hypothesis, popularized with alternative author John Anthony West.
His Sphinx claims are rejected by the scientific consensus in both Egyptology and geology.

The Core Claims Made on the Episode

The Sphinx was carved before 9700 BCE — thousands of years older than the mainstream date of c. 2500 BCE.

An “earlier cycle of civilization” existed before the end of the Younger Dryas and was destroyed by a massive solar outburst.

A secret chamber exists under the left paw of the Sphinx containing “an archive.”

The Great Pyramid complex was built over older, restored structures.

Ancient Egyptian artifacts show evidence of advanced “machining” techniques implying lost technology.

What the Evidence Actually Says

On the Sphinx’s age:

Mark Lehner (Egyptologist, Director of Ancient Egypt Research Associates): “You don’t overthrow Egyptian history based on one phenomenon like a weathering profile… that is how pseudoscience is done, not real science.” Wikipedia summary
Zahi Hawass and James Harrell: Argue the erosion can be explained by post–Old Kingdom weathering of limestone by water-saturated sand cover, salt crystallization from dew, and natural fissures — not Pleistocene-era rainfall. Sphinx water erosion hypothesis — Wikipedia
Geoscientist Jørn Christiansen: Water most likely seeped through natural fissures in the limestone before the Sphinx was carved, making the walls look older than they are. The Archaeologist — Sphinx Erosion Debate
Archaeological context: Limestone quarried from the Sphinx enclosure was used in nearby Fourth Dynasty structures, anchoring the Sphinx to c. 2500 BCE.

On a “lost global civilization”:

No artifacts, settlements, agriculture, writing, metallurgy, or skeletal remains of an advanced pre-9700 BCE civilization have ever been found anywhere on Earth.
Göbekli Tepe (c. 9500 BCE) is impressive but was built by hunter-gatherers — the site shows no evidence of advanced technology, agriculture, or “lost civilization” status. The lead excavators (the German Archaeological Institute) explicitly reject pseudoarchaeological readings of the site. NPR — Gobekli Tepe meets conspiracy theories

On the “secret chamber” under the Sphinx:

Ground-penetrating radar surveys (notably by SRI International and later teams) have found small natural cavities in the bedrock, not engineered chambers or “archives.” No evidence of any artificial chamber containing artifacts has ever been produced.

On Egyptian “machining”:

Tool-mark analysis by archaeologists like Denys Stocks has reproduced the cuts on Egyptian hard-stone artifacts using copper saws, abrasive sand, and tube drills — known Bronze Age techniques.

Joe Rogan’s Role

Rogan does not push back. This is the pattern:

He called the episode “Absolutely one of my favorite podcasts to date…a real mind blower.”
He treats Schoch’s fringe claims as suppressed truth rather than rejected hypotheses.
He invites no Egyptologist or mainstream geologist to rebut the claims, then or in companion episodes.
He folds Schoch’s narrative into his broader “lost civilization” framing that runs through episodes with Graham Hancock, Randall Carlson, and others — building a coherent pseudoarchaeology pipeline for his audience.

To his credit, Schoch himself distances his work from “ancient aliens” content, calling it “a cop-out” and “a business.” But Rogan never makes the equivalent distinction between Schoch’s specific Sphinx claim and the broader unsupported “global lost civilization” narrative he builds in the same conversation.

Why It Matters

Schoch holds a Yale PhD, which lends authority to claims the relevant expert communities have examined and rejected. Audiences hear “geology professor at Boston University” and reasonably assume the claims have mainstream scientific support — they do not.

This episode is a foundational entry in the JRE pseudoarchaeology canon that later helped mainstream attacks on working archaeologists (notably during the Ancient Apocalypse / Hancock controversy) and fuels public mistrust of established historical science.
