The flood recorded in Genesis 6 cannot be proved with absolute certainty, but there is ample evidence to support the view that a global flood did occur. The Bible presents the flood as part of the early history of the world, yet there are certainly skeptics that will reject the evidence.
One evidence of the flood of Noah’s day is the abundance of global flood stories found in a wide variety of cultures. Anthropologists have catalogued hundreds of ancient flood legends from all over the world. The ancient Babylonians, Native Americans, Australian Aboriginals, Aztecs, Romans, Greeks, Chinese, Mayans, Inuits, and many others recorded flood stories. Further, their stories share many similarities to the Genesis account, including an angry god and people who survived the flood in a boat.
A second area of evidence for the flood of Genesis 6 is physical evidence found on the earth’s surface. For example, 75 percent of earth’s land surface is comprised of sedimentary rock—rock that was washed away, dissolved in fluid, and redeposited elsewhere. Fossils are found in many of these sedimentary layers. It is common to find massive fossil graveyards consisting of jumbled, smashed, and contorted fossil remains that give the appearance of a large number of animals destroyed simultaneously by an incredible force.
A third area of evidence for the flood of Noah’s day is the long-distance movement of various types of rock. For example, scientists have noted quartzites discovered more than 300 miles from their source in Oregon, a phenomenon no longer taking place today. The displaced minerals could be the result of what is spoken of in Psalm 104:6–8—the waters standing above the mountains and violently running down into the valleys.
A fourth line of evidence for the global flood is the presence of abundant fossil remains of marine life at the tops of every major mountain range in the world, including the Himalayas. What could have caused this phenomenon? A global flood in which water covered the tallest mountains could explain it. Genesis 7:18–19 notes that “the waters rose and increased greatly on the earth, and the ark floated on the surface of the water. They rose greatly on the earth, and all the high mountains under the entire heavens were covered.” Scientists have yet to provide an adequate alternative theory for the abundance of fossilized marine life at high elevations.
The Bible itself serves as an additional line of support. Time and again, the history of the Bible has been validated through a variety of means. If Scripture is accurate in many other areas of history, why would its account of a global flood be disputed? Taken alongside the evidence from the various global flood narratives, abundant fossils, and high-elevation marine fossils, the Bible’s account offers a plausible scenario for what took place during the time of Noah.
