Underwater Structures: Evidence of Pre-Flood Civilization

Underwater structures found worldwide suggest human construction predating the last major sea level rise, implying civilizations existed before the end of the ice age when sea levels were up to 120 meters lower.

Key sites: Yonaguni Monument off Japan (terraced pyramid-like structure), Bimini Road in the Bahamas (linear stone formation), submerged city of Dwarka off India's coast (matches Hindu texts), the 2001 Cuba underwater city discovery (geometric structures at 700m depth), and various Mediterranean sites.

The debate centers on natural formation versus artificial construction. Dating underwater structures is challenging. However, sea level was demonstrably 120m lower 20,000 years ago, meaning vast areas of currently submerged continental shelf were habitable land. Systematic survey of these areas has barely begun.

Initial probability: 50% that some underwater sites are artificial and genuinely ancient.
