Three decades ago, a Japanese diver discovered a massive stone complex near Yonaguni, at the southwestern-most tip of the Japanese archipelago. Scientists have determined that this structure is man-made and that it must have been built more than 14,000 years ago—a conclusion that led some to seek out more “paranormal” explanations.
The massive structure, first discovered by tour diver Kihachiro Aratake, consists of megalithic stone formations, the largest of which resembles a tiered pyramid the size of two football fields.
The underwater ruins, which lie at depths ranging between 60 and 100 feet below the surface, is considered one of the greatest underwater archeological discoveries in history.
Based on geometric patterns present at the site, scientists have concluded that the formation is not natural. While the structure contains “tons of right angles,” there are also clearly rectangular channels, which lead to stairwells.
According to Graham Hancock, author of the book “Underworld: The Mysterious Origins of Civilization,” the structure, which he believes to be a “ceremonial complex,” was built using a scale of thinking that far surpasses all stone-age civilizations known to us. According to him, the structure was probably built before the thaw of the last ice age, which would have caused massive flooding, a conclusion that would date the structure to over 14,000 years ago.
