In 1992, Griffin wrote and narrated The Discovery of Noah's Ark, based on David Fasold's 1988 book, The Ark of Noah. Griffin's film said that the original Noah's Ark continued to exist in fossil form at the Durupınar site, about from Mount Ararat in Turkey, based on photographic, radar, and metal detector evidence. Griffin also said that towns in the area had names that resembled terms from the Biblical story of the Great Flood. He endorsed the historicity of the Biblical account of the flood, and speculated that the flood was the byproduct of massive tides caused by a gravitational interaction between Earth and a large celestial body coming close to it.
