The Eye of the Sahara, also known as the Richat Structure, is one of the most striking geological formations on Earth. Located in the vast Sahara Desert of Mauritania, this massive circular feature spans about 30 miles (50 kilometers) in diameter.
At first glance, the structure looks like a giant crater or an impact site, but scientists have long debated its true origin. In this article, we’ll explore the scientific explanation behind the Eye of the Sahara, as well as some of the more unusual theories that have emerged over time, including those involving aliens and ancient civilizations.

The Scientific Explanation: A Product of Tectonic Forces and Erosion
From a scientific perspective, the Eye of the Sahara is a result of natural geological processes that have been taking place over millions of years. The formation is believed to have been created by a combination of tectonic forces and erosion, rather than by an asteroid impact or any other sudden catastrophic event.
Around 100 million years ago, during the Cretaceous period, tectonic forces caused the Earth’s crust in the region to uplift, creating a large dome-shaped formation. This uplift caused the rock layers in the area to fold and bend. Over time, these layers of rock became exposed to the forces of erosion, with softer rock layers wearing away much faster than the harder, more resilient layers.
What sets the Eye of the Sahara apart is its concentric ringed structure, which was formed by this differential erosion. As the softer layers eroded away, the harder rock in the center remained intact, creating the distinctive circular formation we see today. The center of the structure consists of hard granite, while the surrounding layers include various types of sedimentary rock that have eroded at different rates.
The process of erosion was further accelerated by wind and water, which over millions of years continued to shape the circular pattern of the formation. While it may seem like the result of a more violent or sudden event, the Eye of the Sahara’s unique shape is a testament to the slow, persistent forces of nature over time.

The Alien Theory: An Extraterrestrial Connection?
Despite the scientific consensus on the formation of the Eye of the Sahara, some alternative theories have emerged that challenge the idea of a purely natural origin. One of the more popular speculative theories is that the Eye of the Sahara is the result of an alien presence or technology, often linked to extraterrestrial activity.
Proponents of this theory point to the structure’s unusual appearance, which they believe could be more consistent with a landing site or some sort of alien technology rather than a natural geological formation. The perfectly symmetrical rings of the Eye are often described as too precise to be the product of random erosion and geological processes, leading some to suggest that the structure may have been artificially created.
There are even some who believe that the Eye of the Sahara could be the remnants of an ancient alien base or a site of extraterrestrial experiments, citing the unexplained nature of its origin. Supporters of this theory often point to the lack of definitive evidence for a natural explanation, claiming that the structure’s size, shape, and complexity are far too advanced for Earth’s natural forces to have created.
While there is no scientific evidence to support this theory, the idea of an alien connection continues to captivate the imaginations of those who are drawn to the mystery of the Eye of the Sahara.

The Ancient Civilization Theory: A Forgotten Connection to Humanity’s Past
Another popular alternative theory is that the Eye of the Sahara was once the center of an ancient, lost civilization. According to this theory, the structure was built by a highly advanced civilization that existed long before recorded history, but whose existence was erased by a cataclysmic event or a dramatic shift in the Earth’s climate.
Supporters of this theory suggest that the concentric rings of the Eye may be evidence of an ancient city or settlement, with the different layers representing the remains of buildings, roads, or other structures. Some even claim that the circular pattern could be a form of symbolic design, potentially linked to astronomical or religious practices of an ancient civilization.
The idea of a lost civilization is often connected to the broader mythology of Atlantis and other ancient societies that supposedly existed and then disappeared without leaving any trace. In this view, the Eye of the Sahara could be one of the few remaining relics of this forgotten past, preserved by time and hidden away in the vast desert.
While there is no direct evidence to support this theory either, it has captured the imagination of many who are fascinated by the idea that our ancestors may have been far more advanced than we realize.

The Impact Crater Theory: A More Explosive Possibility
Before the tectonic and erosion theory gained widespread acceptance, many people believed that the Eye of the Sahara was the result of a massive meteorite impact. The circular shape of the formation, along with the presence of rock layers that appeared to have been displaced, made it seem like an ideal candidate for an impact crater.
However, this theory was eventually debunked when scientists studied the structure in more detail. They determined that the rock layers around the Eye do not show signs of the intense heat and pressure typically associated with meteorite impacts. Additionally, there is no evidence of a large impact crater or shattered rock at the center of the structure. Which further discredits the idea that the Eye of the Sahara was caused by an extraterrestrial impact.
A Geological Enigma Shrouded in Mystery
The Eye of the Sahara remains one of the most fascinating and mysterious geological features on Earth. While the scientific explanation of its formation through tectonic forces and erosion offers a plausible and well-supported understanding of the structure, alternative theories—ranging from alien intervention to ancient civilizations—continue to fuel the imagination of those who seek answers beyond the ordinary.
Whether it is a product of nature or something more enigmatic, the Eye of the Sahara stands as a testament to the complexities of our planet’s geological history and the mysteries that still await discovery.
