What is the Silurian Hypothesis?

The Silurian Hypothesis is a fascinating concept that challenges our understanding of human history and the potential for other intelligent life in the universe. It proposes that advanced civilisations might have existed on Earth long before humans ...

Remarkably, they left no evidence for us to discover. This theory, inspired by an episode of Doctor Who, has sparked scientific discussions. It has opened new avenues for exploration and discovery.

The idea of the Silurian Hypothesis may seem like a work of science fiction, but it is rooted in scientific research and evidence. The theory suggests there may have been other advanced civilisations on Earth that have completely vanished. These civilisations have left no trace for us to find.

This raises an important question: are we the first advanced civilisation on Earth?

One of the main inspirations for the Silurian Hypothesis is the fact that human existence and civilisation are not eternal. Throughout history, great empires and civilisations have risen and fallen, leaving behind only faint traces of their existence.

Take ancient Egypt, for example. For over 3,000 years, the Egyptians thrived. They left behind impressive monuments and artefacts. Yet, in the grand scheme of Earth's history, their civilisation was just a blip.

The Silurian Hypothesis suggests that, given the vast expanse of time that complex life has existed on Earth, it is possible other intelligent species may have risen and fallen before us. This theory challenges our perception of human superiority. It raises the possibility of other advanced civilisations existing in the universe. It also highlights the fragility of human existence and the potential for our civilisation to one day vanish without a trace.

But how can we even begin to search for evidence of ancient civilisations that may have existed millions of years ago? The Silurian Hypothesis proposes looking for indirect markers of industrialization on a global scale. This includes changes in the isotopic composition of elements.

For example, the burning of fossil fuels has altered the carbon isotope ratios in the atmosphere. These changes can be detected in sediment cores. They provide potential evidence of advanced civilisations.

However, the search for ancient civilisations
is not without its challenges

Earth's surface is constantly changing due to plate tectonics. This makes it difficult to find traces of civilisations that may have existed millions of years ago. Fossils, our primary window into ancient life, are also rare. Specific conditions are needed for fossilization to occur. This means that the odds of finding evidence of a short-lived species like humans in the fossil record are slim.

Despite these challenges, scientists continue to explore the possibility of ancient civilisations on Earth and beyond. The Silurian Hypothesis provides a framework for searching for these civilisations not just on Earth, but also on other planets.

The Drake Equation estimates the number of extraterrestrial civilisations in our galaxy. It suggests that there could be anywhere from 150,000 to 1.5 billion. If intelligent life can arise multiple times on a single planet, as the Silurian Hypothesis proposes, it opens up exciting possibilities for finding civilisations throughout the galaxy.

Mars and Europa, one of Jupiter's moons, are prime candidates for such investigations

Mars, once warmer and wetter, may have supported life in the past. It could potentially hold evidence of ancient civilisations. Europa, with its saltwater ocean, is also promising for the search for extraterrestrial life. The Silurian Hypothesis not only applies to Earth, but also provides a framework for exploring other planets in our solar system and beyond.

The Silurian Hypothesis is a thought-provoking theory that challenges our understanding of human history and the potential for other intelligent life in the universe. While it does not prove the existence of ancient civilisations, it opens up exciting possibilities for exploration and discovery.

As we continue to search for answers about our past and the existence of other advanced civilisations, the Silurian Hypothesis will remain a fascinating and thought-provoking concept.

Based in the charming village of Hanslope in Buckinghamshire, UK, I bring over 30 years of experience in web development. From creating my first website for the Open University in 1993, through being part of the dot com boom, to my explorations in SaaS and AI over the last few years, my journey has been a rich tapestry of web projects, big and small, both funded and bootstrapped. Originally developed during the pandemic, at the start of 2025, I released the next iteration of YourPCM, version 2, which is all about 'Easy Contact Management for Small Business Owners'.
