Ancient calendar, recently discovered, may document a long-ago disaster

Researchers at Gobekli Tepe in southern Turkey have potentially uncovered the world's oldest lunisolar calendar, which may document a significant astronomical event. Martin Sweatman from the University of Edinburgh suggests that V-shaped markings on a pillar at the site correspond to a comet strike that occurred around 10,850 B.C., leading to a 1,200-year ice age and the extinction of many large animals. This discovery aligns with Sweatman's previous research linking the site to the comet impact. The calendar appears to track the lunar cycle and consists of 365 days, divided into 12 lunar months and additional days. The findings have sparked debate among archaeologists, with some questioning the interpretation of the markings. Sweatman argues that the carvings indicate ancient humans were capable of recording celestial observations, reflecting the importance of the comet event in their lives. The research highlights the potential for ancient peoples to document time and seasonal changes, providing insight into their understanding of the cosmos.
