* Updated throughout with recent developments and additional illustrations

* Reveals how solar outbursts caused the end of the last ice age, unleashed catastrophe upon ancient advanced civilizations, and led to six millennia of a Solar-Induced Dark Age

* Includes evidence from solar science, geology, oceanic circulation patterns, the Sphinx, the underground cities of Cappadocia, the Easter Island rongorongo glyphs, and the Gobekli Tepe complex in Turkey

In this newly revised and expanded edition, updated throughout with recent developments, geologist Robert Schoch builds upon his revolutionary theory that the origins of the Sphinx date back much further than 2500 BCE and examines scientific evidence of the catastrophe that destroyed early high culture nearly 12,000 years ago.

Combining evidence from multiple scientific disciplines, Schoch makes the case that the abrupt end of the last ice age, circa 9700 BCE, was due to an agitated Sun. Solar outbursts unleashed electrical/plasma discharges upon Earth, triggering dramatic climate change as well as increased earthquake and volcanic activity, fires, high radiation levels, and massive floods. Schoch explains how these events impacted the civilizations of the time, set humanity back thousands of years, and led to six millennia of a Solar-Induced Dark Age (SIDA). Applying the SIDA framework to ancient history, he explores how many megalithic monuments, petroglyphs, indigenous traditions, and legends fall logically into place, including the underground cities of Cappadocia, the Easter Island rongorongo glyphs, and the Gobekli Tepe complex in Turkey. He also reveals that our Sun is a much more unstable star than previously believed, suggesting that history could repeat itself with a solar outburst powerful enough to devastate modern society.

Weaving together a new view of the origins and antiquity of civilization and the dynamics of the planet we live on, Schoch maintains we must heed the megalithic warning of the past and collectively prepare for future events.

New research and evidence that the Sphinx is thousands of years older than previously thought

* Contrasts what Egyptologists claim about the Sphinx with historical accounts and new research including reanalysis of seismic studies and updates to Schoch’s water weathering research and Bauval’s Orion Correlation Theory

* Examines how the Sphinx is contemporaneous with Gobekli Tepe, aligned with the constellation Leo, and was recarved during the Old Kingdom era of Egypt

* Reveals that the Sphinx was built during the actual historical Golden Age of ancient Egypt, the period known in legend as Zep Tepi

No other monument in the world evokes mystery like the Great Sphinx of Giza. It has survived the harsh climate of Egypt for thousands of years and will remain long after our own civilization is gone. According to orthodox Egyptology, the Sphinx was built around 2500 BCE as a memorial to the pharaoh Khafre. Yet this “fact” has scant to no supportive evidence. When was the Sphinx really built and, most importantly, why?

In this provocative collaboration from two Egyptology outsiders, Robert M. Schoch, Ph.D., and Robert Bauval combine their decades of research to show how the Sphinx is thousands of years older than the conventional Egyptological timeline and was built by a long forgotten pre-Pharaonic civilization. They examine the known history of the Sphinx, contrasting what Egyptologists claim with prominent historical accounts and new research, including updates to Schoch’s geological water weathering research and reanalysis of seismic studies. Building on Bauval’s Orion Correlation Theory, they investigate the archaeoastronomical alignments of the monuments of the Giza Plateau and reveal how the pyramids and Sphinx were built to align with the constellations of Orion and Leo. Analyzing the evidence for a significantly older construction phase at Giza and the restoration and recarving of the Sphinx during the Old Kingdom era, they assert that the Sphinx was first built by an advanced pre-Pharaonic civilization that existed circa 12,000 years ago on the Giza Plateau, contemporaneous with the sophisticated Gobekli Tepe complex.

The authors examine how the monuments at Giza memorialize Zep Tepi, the Golden Age of legend shown here to be an actual historical time period from roughly 10,500 BCE through 9700 BCE. Moving us closer to an understanding of the true age and purpose of the Great Sphinx, Schoch and Bauval provide evidence of an early high civilization witnessed by the Great Sphinx before the end of the last ice age.
