The monument was carved under skies that rained on it. Egypt's skies have been dry for thousands of years. Either the monument is older than they say, or the climate was wetter than they say. The evidence says both. — Robert M. Schoch

Biographical Context and the Academic Position

Robert M. Schoch is an American geologist and a full-time faculty member at the College of General Studies at Boston University, where he has taught since 1984. His academic credentials — a Ph.D. in geology and geophysics from Yale, tenure at a major research university, peer-reviewed publications in sedimentology and stratigraphy — place him in an unusual position within catastrophist research. Most researchers pursuing catastrophist hypotheses operate outside the academic apparatus, either because they entered the field through non-academic routes (Hancock) or because their hypotheses have been insufficiently welcome within institutional departments (Velikovsky). Schoch is one of the few academic scientists with standing institutional credentials who has pursued catastrophist research seriously, and his position has made him both unusually credible and unusually vulnerable to professional consequences when his conclusions have challenged consensus positions.

His entry into the catastrophist question came through an invitation from the independent researcher John Anthony West, who in 1990 asked Schoch to apply geological methods to the question of the Great Sphinx’s age. West had become convinced, drawing on the earlier work of Schwaller de Lubicz, that the weathering patterns on the Sphinx indicated exposure to substantial rainfall over a prolonged period — weather inconsistent with the arid climate that has prevailed in Egypt since approximately the end of the African Humid Period around 5,000 years ago. West needed a credentialed geologist to examine the monument and to determine whether his hypothesis was defensible. Schoch agreed to conduct the investigation under the condition that he would report whatever he found, regardless of its consistency with West’s prior expectations.

The Sphinx Water Erosion Evidence

Schoch’s field investigation of the Sphinx, conducted in 1990 and 1991 and formally reported at the 1991 Geological Society of America annual meeting, documented weathering patterns on the body of the Sphinx and on the walls of the enclosure in which it sits that Schoch interpreted as characteristic of water erosion rather than of wind erosion. The specific features — vertical fissures, rounded profiles, undulating weathered surfaces — are consistent with erosion by running water of substantial duration, and are inconsistent with the appearance of monuments that have weathered only under wind and sand in a dry climate. The other monuments on the Giza plateau that were unambiguously constructed during the Old Kingdom period, roughly 4,500 years ago, show very different weathering patterns consistent with wind exposure rather than water.

The implication of this observation, if the interpretation is correct, is that the original carving of the Sphinx must predate the onset of the current arid climate in Egypt by a substantial margin. The conventional dating of the Sphinx to the reign of Khafre in the Fourth Dynasty, approximately 2500 BCE, is incompatible with the weathering observed, because Egypt had already been dry for at least 2,000 years by that date. Schoch’s geological estimate, based on the extent of the weathering and on assumptions about the rate of erosion under typical conditions, placed the original carving of the Sphinx somewhere between 7,000 and 5,000 BCE at the most recent, and potentially substantially earlier.

This conclusion brought Schoch into direct conflict with Egyptological consensus, which had been committed to the Khafre dating for more than a century and which treated the question as settled. The response from the Egyptological community was rapid and hostile. Schoch’s geological analysis was challenged primarily on the grounds that other geologists had not reached the same conclusions and that the weathering could be explained by processes other than the one Schoch proposed. The Egyptological argument — that the Sphinx must have been built by Khafre because it is located near his pyramid and is stylistically consistent with his reign — was reasserted without direct engagement with the specific geological evidence Schoch had presented.

Forgotten Civilization and the Solar Outburst Hypothesis

Forgotten Civilization: The Role of Solar Outbursts in Our Past and Future (2012, updated 2021) extends Schoch’s research into a broader framework connecting the evidence for a pre-dynastic civilization with a specific proposed cause for its destruction. The book argues that a sophisticated civilization existed in the eastern Mediterranean and adjacent regions during the last ice age, that it was responsible for the original carving of the Sphinx and for related monuments now partly or wholly destroyed or buried, and that this civilization was destroyed by a massive solar outburst event at or near the end of the Younger Dryas period approximately 11,600 years ago.

The solar outburst hypothesis Schoch develops is independently derived from his own analysis of the physical record, particularly the evidence from plasma physicist Anthony Peratt concerning ancient petroglyphs that appear to depict high-energy plasma discharges in the sky. Peratt’s morphological analysis, published in peer-reviewed plasma physics literature, documents that petroglyphs from sites across multiple continents share a common set of specific features that match the predicted appearance of a high-current plasma column as it would be observed from the Earth’s surface. The features are specific enough — and the consistency across geographically and culturally distant sites is high enough — that the simplest explanation is direct observation of a common event visible simultaneously across the ancient world.

Schoch integrates this plasma evidence with the tree-ring and ice core evidence of anomalous cosmic-ray events in the historical record (the 774–775 CE spike and related events), with the geological and archaeological evidence of the Younger Dryas boundary, and with the mythological record of events involving fire from the sky. The resulting synthesis proposes that a major solar outburst event occurred at the end of the Younger Dryas, that it was of sufficient magnitude to destroy the pre-existing civilization, and that the survivors carried fragmentary knowledge into the populations that would eventually found the historical civilizations of the Near East.

The hypothesis overlaps substantially with the independent work of Ben Davidson and the Suspicious Observers project. Schoch and Davidson have collaborated on documentaries and conference presentations, with Schoch providing the geological and archaeological foundation and Davidson providing the contemporary observational data on solar behavior. The convergence between their work, reached through different methodologies, is one of the stronger pieces of evidence for the broader framework of solar-driven cataclysm.

The Gobekli Tepe Connection

Schoch’s research has also engaged extensively with Gobekli Tepe as potential evidence for the pre-cataclysm civilization. The dating of the site to approximately 9600 BCE places its construction within a few centuries of the end of the Younger Dryas and within the window Schoch had independently proposed for the pre-cataclysm civilization. The sophistication of the site — the geometric precision of its T-shaped pillars, the zoomorphic reliefs suggesting a developed iconographic tradition, the scale of the construction project — is inconsistent with the conventional narrative of hunter-gatherer populations slowly transitioning to agriculture and eventual civilization.

On Schoch’s reading, Göbekli Tepe is best understood as the work of survivors of the pre-cataclysm civilization, carrying forward elements of an older tradition into the post-cataclysm world and constructing a monumental site that would preserve aspects of the older knowledge. The deliberate burial of the site, confirmed by the archaeology of the complex, takes on a specific meaning in this framing. It represents a considered act of preservation — sealing the monument against the known recurrence and against the erosion of time, to be recovered by a future civilization capable of reading what it had preserved.

The integration of Göbekli Tepe with the Sphinx and with the solar outburst hypothesis forms a coherent narrative about the deep history of the eastern Mediterranean that departs substantially from the conventional account while remaining grounded in specific material evidence. The narrative is not beyond challenge — specific elements can be and have been disputed — but the overall framework is tight enough to merit serious engagement rather than the dismissal it has generally received from institutional Egyptology and Quaternary science.

The Institutional Response and Its Implications

Schoch’s academic position has insulated him from some of the professional consequences that less credentialed catastrophist researchers have faced, but it has not protected him from the broader pattern of institutional hostility to his conclusions. His specific claims about the Sphinx have been repeatedly misrepresented in Egyptological literature and in popular coverage, with the geological evidence he presented either ignored or addressed through arguments that do not engage with the specific features he documented. The broader catastrophist framework he has developed has been received with similar institutional resistance.

The value of Schoch’s work for catastrophist research lies substantially in the fact that he is an accredited academic scientist whose conclusions match those reached by researchers operating outside the institutional apparatus. The convergence between his work and that of Graham Hancock, Randall Carlson, Ben Davidson, and the Younger Dryas impact researchers constitutes evidence that the catastrophist conclusions are not artifacts of amateur methodology but are supported by evidence that holds up under rigorous professional examination. The institutional resistance to these conclusions, in the face of their convergent support from researchers with different training and methods, points to something other than the ordinary processes of scientific adjudication.
