According to scientist Robert Ballard, renowned for his work on underwater wrecks, the flood episode is based on real historical events. While digging in the Black Sea, his team found evidence of the catastrophe indicating that a wall of water from the Mediterranean Sea fell on a part of the Balkans with a force two hundred times greater than Niagara Falls. Robert Ballard and his team discovered the remains of an ancient coastal shoreline 400 metres below the Black Sea.nnnRobert Ballard links this discovery to the flood narrated in Genesis, explaining that such a traumatic episode must have been told and passed on from generation to generation until it became the story of the flood myth.nn
