Could the builders of Göbekli Tepe and Karahan Tepe have encoded warnings of cosmic catastrophe into stone, preserving humanity’s earliest attempt to understand and survive Earth’s violent, recurring cycles?
Göbekli Tepe and Karahan Tepe, two of the most enigmatic archaeological sites in Turkey, may hold clues to ancient civilizations' awareness of cyclical geophysical events. These sites, dating back more than 12,000 years, were built at the end of the last Ice Age, a period marked by dramatic climate shifts and possible cosmic events. The Younger Dryas period (circa 10,900–9,700 BCE), a sudden return to glacial conditions, coincided with the estimated construction of these sites, suggesting that their builders may have been responding to global environmental changes.
One theory proposes that Göbekli Tepe and Karahan Tepe were constructed as sanctuaries or observatories to monitor cosmic and geophysical cycles. Dr. Martin B. Sweatman suggested that carvings on Göbekli Tepe’s T-shaped pillars, including depictions of animals and symbols, might encode astronomical knowledge or records of past cataclysms. His work aligns with the Younger Dryas Impact Hypothesis, which argues that a comet impact event around 10,850 BCE triggered the Younger Dryas cooling event. This theory, originally proposed by Dr. Richard Firestone, Dr. James Kennett, and Dr. Allen West, suggested that fragments of a disintegrating comet impacted North America and other regions, causing climate disruptions and mass extinctions. Some researchers believe the Vulture Stone (Pillar 43) at Göbekli Tepe may depict a record of this cosmic event.
Geological evidence also suggests that these sites may have experienced seismic activity over millennia. Turkey lies in a region prone to earthquakes, and the deliberate burial of Göbekli Tepe remains an unsolved mystery. Some researchers, such as Klaus Schmidt, the German archaeologist who led early excavations at Göbekli Tepe, hypothesized that it was intentionally buried by its builders, possibly to preserve its knowledge for future generations or due to shifting environmental conditions.
Karahan Tepe, though less studied, shares architectural and symbolic elements with Göbekli Tepe, reinforcing the idea that these sites functioned as part of a larger network designed to observe or commemorate major geophysical cycles. Some researchers, such as Dr. Eylem Özdoğan, propose that Karahan Tepe’s carvings and humanoid figures may represent an earlier phase of Neolithic spirituality. The possibility that these ancient sites were linked to knowledge of past disasters suggests a sophisticated awareness of Earth’s dynamic and sometimes violent changes.
Göbekli Tepe’s T-shaped megalithic pillars, some adorned with detailed carvings of animals and symbols, may encode information about past astronomical events. Some researchers, such as those analyzing the Vulture Stone (Pillar 43), suggest that the engravings depict star constellations and record a cataclysmic comet impact that could have triggered the Younger Dryas period (~10,900 BCE). This theory aligns with the idea that ancient civilizations observed and documented major cosmic disruptions that shaped their environment.
A particularly intriguing mystery is the deliberate burial of Göbekli Tepe. Unlike other ancient sites that fell into ruin over time, this one was systematically covered with sediment around 8,000 BCE, an act that suggests intentional preservation. Theories suggest that its builders may have buried it to protect it from a looming catastrophe, such as an anticipated cosmic impact, solar storms, or climate changes. Others propose that it was sealed as a time capsule, preserving knowledge for future generations who might experience similar events.
Karahan Tepe, featuring carvings, stone circles, and subterranean structures, shares architectural similarities with Göbekli Tepe, reinforcing the idea that both sites were part of an ancient network of knowledge centers. If they were indeed built in response to past cataclysms, they may represent some of the oldest evidence of humanity’s attempt to understand and survive Earth’s cyclical upheavals.
Göbekli Tepe and Karahan Tepe may have served as astronomical observatories, tracking cosmic cycles and warning of potential cataclysms. The precise alignments of these megalithic structures suggest that their builders had advanced knowledge of celestial movements, possibly linking them to cycles of destruction caused by cosmic events such as solar activity, comet impacts, and planetary precession.
One of the most compelling pieces of evidence supporting this theory is the Vulture Stone (Pillar 43) at Göbekli Tepe, which some researchers interpret as a star map documenting a significant cosmic event. Certain carvings on the pillar resemble known constellations, and some scholars, including those studying the Younger Dryas Impact Hypothesis, propose that it records a comet impact around 10,900 BCE, an event believed to have triggered sudden climate change and widespread extinctions. If true, this suggests that the site’s builders not only observed astronomical cycles but also recorded catastrophic events for future generations.
Both Göbekli Tepe and Karahan Tepe may also be connected to the precessional cycle of the Earth, which affects the position of stars over time. Ancient civilisations often tracked this cycle to predict long-term cosmic changes, believing that shifts in celestial alignments signaled impending disasters. Solar activity, such as extreme solar flares or geomagnetic storms, could also have been observed and recorded, potentially explaining why ancient mythologies frequently associate celestial events with destruction and rebirth.
If these sites functioned as warning systems, they reinforce the idea that early civilizations recognized and recorded patterns of cosmic upheaval. Their alignment with celestial bodies may indicate an attempt to track and predict cycles of destruction, ensuring that knowledge of these events survived even after civilizations perished.
Göbekli Tepe and Karahan Tepe are two of the most significant prehistoric sites, believed to date back to around 9600 BCE. While traditionally studied for their archaeological and cultural significance, recent research has explored the possibility of their connection to cyclical geophysical events and ancient astronomical knowledge.
Several studies have examined whether these sites served as observatories for tracking cosmic cycles. Some researchers suggest that the carvings and symbols at Göbekli Tepe may represent astronomical alignments, possibly recording events like solar cycles, equinoxes, or even cometary impacts. A study in 2024 proposed that some enclosures at the site functioned as calendrical markers, potentially indicating early forms of timekeeping based on celestial movements.
At Karahan Tepe, ongoing excavations have revealed T-shaped pillars similar to Göbekli Tepe, along with intricate carvings. Some researchers argue that Karahan Tepe might predate Göbekli Tepe, providing further insights into the transition from hunter-gatherer societies to early settled civilizations. Geophysical surveys conducted at these sites have uncovered subterranean structures, indicating that both sites may have been part of a larger network of ritual centers.
While there is no conclusive evidence linking these sites to cyclical geophysical events such as pole shifts or cosmic cataclysms, alternative researchers have speculated that they could be linked to global disasters, possibly encoded within their structures.
What do the enigmatic structures and carvings at Göbekli Tepe and Karahan Tepe reveal about the ancient builders’ knowledge of cosmic cycles and their response to cataclysmic events?
This evocative artwork portrays a powerful visual interpretation of the Younger Dryas Impact Hypothesis as it might have been encoded in ancient stone. Set against the warm hues of the golden hour, Pillar 43, one of Göbekli Tepe’s most iconic monoliths, stands solemnly as meteors streak across the twilight sky. The vulture symbol, central to the pillar’s carvings, glows ethereally, aligning with constellations above, hinting at celestial messages preserved for millennia.
Rendered in an ultra-detailed archaeological illustration style, the scene bridges science, myth, and memory, suggesting that ancient peoples may have witnessed a cataclysmic event and immortalized it in stone. The illustration captures not only the artistic sophistication of early civilization but also the possibility that Göbekli Tepe served as a sky-watching monument, warning of a cosmic catastrophe that reshaped the world.
Researchers Andrew Collins, JJ Ainsworth, and colleagues discovered a winter solstice sunrise alignment at Karahan Tepe in December 2021, later confirmed with further observations in 2022. This alignment involves sunlight illuminating a carved human-like head within the AB pit, possibly through a porthole stone connecting it to a larger enclosure. The alignment is thought to date back to around 9000 BCE, making it one of the oldest known solar-aligned structures. Collins had previously identified a summer solstice sunset alignment at the site as well. These discoveries suggest a sophisticated understanding of celestial cycles by the site's builders.
Excavations only began in 2019, yet Karahan Tepe is already yielding remarkable astronomical insights, potentially surpassing Göbekli Tepe in scale and significance. The team used archaeoastronomy software like Stellarium to confirm the accuracy of alignments in the ancient sky. The findings hint at the site's ritual or shamanic function, possibly tied to cosmic beliefs and solar worship.
Graham Hancock explores the widespread global myths of a cataclysmic flood, arguing they may reflect a real event rather than isolated local disasters. He identifies the Younger Dryas period (~12,800 years ago) as the most likely candidate for a time of abrupt climate shifts, sea level rise, and mass extinctions.
Hancock challenges mainstream archaeology’s view that ancient flood myths stem from local floods exaggerated over time. Instead, he supports the Younger Dryas Impact Hypothesis, which suggests a cosmic impact triggered global devastation. This theory, backed by over 60 scientists across disciplines, is supported by geological evidence such as a dark sediment layer found in places like Murray Springs, Arizona. This layer contains soot, melted quartz, nano-diamonds, and carbon microspherules, signs of intense heat and an extraterrestrial event.
Hancock suggests such a catastrophe would have left a deep imprint on early human societies, giving rise to shared cultural memories of a great flood and a lost world, found in myths worldwide.
About four years ago, NASA radar mapping revealed a massive crater beneath Greenland’s ice, sparking renewed interest in the Younger Dryas Impact Hypothesis (YDIH). This theory suggests that a comet or asteroid struck Earth around 12,900 years ago, triggering a sudden cooling period (the Younger Dryas), widespread wildfires, and the extinction of many Ice Age animals. Proponents also cite supporting evidence like microspherules, platinum anomalies, and a distinct sediment layer known as the “black mat.”
Though only a minority of scientists support the YDIH, the dramatic nature of the idea has captured public and media attention. Most researchers favor simpler explanations, such as glacial meltwater disrupting ocean currents. The narrator, initially skeptical, recently came across a comprehensive scientific paper that directly refutes all major claims of the impact theory. The paper argues convincingly that the Younger Dryas cooling and associated extinctions likely had other causes, not an extraterrestrial impact casting serious doubt on the validity of the YDIH.
The video explores the Younger Dryas Impact Hypothesis (YDIH) and its connection to theories of a lost advanced civilization destroyed by a cataclysm at the end of the last Ice Age. The channel, active since 2019 and focused on ancient artifacts from the past 5,000 years, typically avoids such speculative topics. However, due to persistent viewer interest, the creator decided to investigate the YDIH more deeply.
The Younger Dryas was a sudden cooling period between 12,900 and 11,700 years ago, mainly affecting the Northern Hemisphere. The hypothesis suggests that this was triggered by fragments of a massive comet striking Earth, causing wildfires, floods, and mass extinctions. Proponents of alternative history theories use this as a possible explanation for the disappearance of a lost civilization, although the hypothesis doesn’t directly support their timelines or flood myths.
Most experts remain skeptical of the YDIH, and this video seeks to understand whether their criticisms are scientifically grounded or overly dismissive of new ideas.
