Description: An intriguing thought experiment on being able to recognize very ancient traces of extraterrestrial life and civilizations involves what is known as the “Silurian hypothesis,” which involves how to identify traces of industrial civilizations millions of years in Earth’s past. If, and this is definitely an “if,” terrestrial life had developed sentience millions of years before humanity, traces of these sentients’ technology and industry may not be recognizable as such, depending upon both geological metamorphosis and distortion and decomposition of metals and other artificial components. Another aspect is that, thanks to constant erosion of Earth’s surface and plate tectonics raising new mountains and plateaus, what were prime locations for cities during the Cretaceous period (145 million years BCE to 65 million years BCE) could have eroded to dust or been subducted into Earth’s mantle, destroying them forever. However, and this is another “if,” if an advanced civilization had existed on Earth in the distant past, its artifacts and relics may still be preserved in a recognizable form, but were preserved in sedimentary strata currently covered with lava flows, buried under glaciers, or are otherwise inaccessible at this time.
