Building upon his revolutionary theory that the Sphinx dates back much further than 2500 BCE, geologist Robert Schoch reveals scientific evidence of advanced civilization predating ancient Egypt, Sumeria, and Greece, as well as the catastrophe that destroyed it nearly 12,000 years ago and what its legacy can teach us about our own future. Combining evidence from multiple scientific disciplines, Schoch shows how the last ice age ended abruptly in 9700 BCE due to coronal mass ejections from the Sun. These solar outbursts unleashed electrical/plasma discharges upon Earth and triggered volcanic activity, earthquakes, fires, and massive floods as glaciers melted and lightning strikes released torrential rains from the oceans. He explains how these events eradicated the civilization of the time and set humanity back thousands of years, only to reemerge around 3500 BCE with scattered memories and nascent abilities. He explores within this framework, how many megalithic monuments, underground cities, and ancient legends fall logically into place, as well as the reinterpreted Easter Island rongorongo texts and the intentional burial, 10,000 years ago, of the Goebekli Tepe complex in Turkey. Schoch reveals scientific evidence that shows how history could repeat itself with a coronal mass ejection powerful enough to devastate modern society. Weaving together a new view of the origins of civilization, the truths behind ancient wisdom, 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.
