Exploring the Possibility of Prehistoric Civilizations on Earth and Their Impact on the Anthropocene
- The Silurian Hypothesis examines the possibility that humans are not the first advanced civilization on Earth
- Plate tectonics, erosion and fossilization make it difficult to uncover evidence of ancient civilizations
- Homo sapiens have only been around for about 100,000 years, while complex life has existed for 600 million years
- Archaeology shows that many civilizations have risen and fallen within a few thousand years
- Anthropocene sedimentary cores provide evidence of human activity that can be detected in future centuries
- Combustion of fossil fuels has caused a Seuss effect which is detectable in carbon isotope ratios.
Possibility of Prehistoric Advanced Civilizations Revealed Through the P-E-T-M
- The Paleocene-Eocene Thermal Maximum (P-E-T-M) was a global change in carbon and oxygen isotope levels 56 million years ago that lasted around 200,000 years
- The temperature rose 6 degrees Celsius, likely caused by a massive volcanic eruption, although this is unknown
- The Silurian Hypothesis suggests the possibility of other advanced civilizations existing on Earth millions of years ago, as well as on other planets in the galaxy
- This can be estimated using the Drake Equation
- Humans may be unique, but there could be millions of other civilizations out there to discover.
