In the waters of Cabo de San Antonio off of the Cuban coast, research is being conducted on what preliminary research may suggest are underwater ruins and the remains of a lost civilization, perhaps more than 6,000 years old. This is in line with many other underwater discoveries arising both off the coast of India in addition to controversial underwater discoveries elsewhere around the globe that are rattling the scientific community and provoking much discussion surrounding the previously established timelines regarding the progression of human civilization.

Ulises, a research vessel hired by the Castro government to investigate oil, gas, in addition to any potential treasure finds, stumbled across the find during the summer of 2000. Due to the magnitude of the results of initial sonar mapping in addition to the precise nature of the perfect alignment of corridors and stone blocks, initial observers proposed a potential underwater military installation. It was not until an additional six months of observation and research that researchers began to propose the findings supported a hypothesis of a lost ancient civilization far beneath the ocean. Not only does the civilization potentially far predate the ancient Maya of the Yucatan, the nature of the discovery being near 2,000 feet below the surface of the ocean present other complexities.

The complexities of the find present additional questions, which necessitate solid conclusions before any conjectures should be formulated. One, the nature of the depth of the structures raises questions surrounding the demise of any potential civilization. The early research additionally indicates structures made of granite, a building component which would have been foreign to that part of the early world, as granite does not exist naturally in Cuba or the Yucatan, and is typically found in Central Mexico. Any additional research which would verify conclusions surrounding a lost civilization would also align with some of the oral traditions passed on by the Maya and native Yucatecos which tell of an ancient island inhabited by early ancestors lost beneath the ocean.

Underwater Ruins Somewhat more controversial in nature, not far from Taiwan Pacific waters off the coast of the Japanese island of Yonaguni are what could potentially be the remains of a 5,000-year-old expansive city. Initially discovered in 1986, a local diver came across what is now known as the Yonaguni formations. Large stone structures underwater potentially feature a castle, pyramids, and temples, in addition to a stadium. Early suggestions propose the expansive terrain may have been submerged by a significant tsunami event which is typical of the location.

Some experts continue to remain skeptical, offering proposals of naturally occurring formations, as some areas geologically consistent with high tectonic and fault activity will produce large geological formations with very straight edges which may appear as though manmade. One of the significant issues in verifying any potential assumptions surrounding the Yonaguni remains due to the lack of any government initiatives in providing any additional research, as a result much of the early research on these formations has been provided by individuals who are naturally drawn by the fascination of these underwater mysteries.

Masaaki Kimura, a marine geologist at the University of the Ryukyus in Japan, continues to remain absolutely convinced these monuments are the craftsmanship of a forgotten civilization. Diving at the site for a period of 15 years, Kimura has been mapping and measuring the underwater formations. One of the larger structure projects from the ocean floor at a height of 25 meters, appearing as though an immense underwater monolith.

Some skeptics of the reports by individual divers have changed their perspective upon visiting the site, with Toru Ouchi, an associate professor of seismology at Kobe University stating, that upon visiting the underwater formations, it becomes clear these are manmade structures, as there exist no precedent for natural occurring formations to be crafted in such a precise manner. Not surprisingly, sharing a resemblance with other locations around the globe, some of the locals believe the Yonaguni formations to be remains of Mu, a lost civilization told to have vanished beneath the ocean, during cataclysmic events.

As is typically the case occurring in any significant revision of a generally accepted scientific consensus, more evidence is necessary for any solid conclusions surrounding what may be far more advanced ancient human civilizations. However as discoveries continue to arise around the globe many within the archeological community are being forced to take a closer inspection of some of the claims that have typically been dismissed as lacking in any substantial foundation. Early research begins to indicate mankind may have been far more technologically advanced than previously known. Thousands of years prior to what has generally been accepted amongst the archeological community as the cradle of civilization, the evidence is beginning to support the supposition of forgotten ancient advanced civilizations scattered across the globe.
