Is the 10k-Year-Old Yonaguni Monument a Man-Made Marvel or Nature's Art?

Nestled along the southern coast of Yonaguni, Japan, are enigmatic submerged ruins that have captured the fascination of researchers and ignited fervent debates. Believed to date back approximately 10,000 years, the origin of the Yonaguni monument remains shrouded in mystery. Hotly debated among experts, some asserting that these formations are unmistakably man-made, while others, adopting a more conservative stance, attribute their creation to the forces of natural phenomena. This intriguing archaeological site continues to be a subject of exploration, sparking curiosity and speculation about its true origins.

The unique and awe-inspiring site was discovered in 1995 by a diver who strayed too far off the Okinawa shore and was dumb-struck when he stumbled upon the sunken arrangement of monolithic blocks"as if terraced into the side of a mountain". Professor Masaaki Kimura, a marine seismologist of the University of the Rykyus, also pointed out a number of marks, such as a plus sign and a V shape, that appear to show that human beings worked the stone and could have been made by wedge-like tools called kusabi. Hancock draws parallels between Yonaguni and other ruins found beneath the waters of Lake Titicaca and in Dwarka, off the coast of India, which offer further evidence for the existence of a vast underwater world containing structures stretching back to the dimmest chapters of human antiquity.
