the Lost City of Atlantis (theoretical)

The Lost City of Atlantis is a legendary civilization first mentioned by the ancient Greek philosopher Plato around 360 B.C. He described it as a powerful and advanced society that existed about 9,000 years before his time, located beyond the "Pillars of Hercules" (now the Strait of Gibraltar). According to Plato, Atlantis eventually sank into the ocean due to a cataclysmic event, serving as a cautionary tale about hubris and moral decay. Over the years, many theories have emerged about its possible location and existence, but no definitive evidence has been found, making it a captivating myth and a symbol of lost knowledge.
