Göbekli Tepe in southern Turkey, a 12,000-year-old site, is home to what experts believe is the world’s oldest known calendar. This ancient complex, predating Stonehenge by millennia, features stone pillars adorned with intricate carvings that record astronomical events.

The calendar marks significant celestial patterns and reportedly reflects a sophisticated understanding of the cosmos.

Unraveling the Mystery of V-Shaped Symbols

Researchers have decoded V-shaped symbols on the pillars, each representing a single day. By counting these symbols, they discovered a solar calendar of 365 days, consisting of 12 lunar months plus 11 extra days.

Marking the Summer Solstice

A special V-shaped symbol, worn around the neck of a bird-like figure, represents the summer solstice. This unique marking indicates the importance of the solstice in their calendar, emphasizing how early humans used astronomical events to track time and seasons.

Such symbols were likely crucial for agricultural and ritual purposes.

Commemorating a Catastrophic Event

The carvings at Göbekli Tepe are also believed to memorialize a devastating comet strike around 10,850 BC.

This event triggered a mini-ice age lasting over 1,200 years, drastically altering the environment and pushing ancient humans to adapt.

A Shift Towards Civilization

In response to the harsh conditions brought by the comet strike, early humans began to shift from a hunter-gatherer lifestyle to agriculture.

Evidence of Early Precession Knowledge

The carvings at Göbekli Tepe suggest that ancient people understood precession — the wobble in Earth’s axis affecting constellation movements — long before it was documented by the Greek astronomer Hipparchus in 150 BC.
