Genesis flood narrative

The Genesis flood narrative is a Hebrew flood myth. It appears in Chapters 6 to 9 of the Book of Genesis in the Old Testament of the Bible. 

Most of the book of Genesis was probably written around the 5th century BCE. Some parts, including the flood story, may have been written as late as the 3rd century BCE.

 The myth 
In the Genesis flood myth, God is unhappy with humans and wants to undo some of his creation and start over. He warns Noah to build an ark and fill it with his family and two of each animal on earth. Then he floods the earth. Nobody survives except for Noah and his family members on the ark.

 Interpretations 
Scientists agree that there was no global flood event that wiped out all human and animal life. The global distribution of species is one clue: species did not spread from one single place, as the story would suggest. 

One branch of creationism argues that the Genesis flood narrative is based on fact, and that a global flood did occur. 

The Genesis flood narrative has also been interpreted as the story of a local flood event, like the Black Sea deluge.

Some people relate the Biblical flood myth to the climate change phenomena associated with the Piora Oscillation, which triggered the collapse of the Uruk period.Lamb, p. 128.

 Research 
Academic scholars and researchers think the flood myth is very unlikely, or at least quite exaggerated. They say a flood of that size, with just a few human and animal survivors, would cause a severe genetic bottleneck. There is no evidence that this happened at the time (roughly 7000 years before the present day), either among humans or other animal species.Naturalis Historia blog. "The Great Genetic Bottleneck that Contradicts Ken Ham’s Radical Accelerated Diversification (Post-Flood Hyper-Evolution)." https://thenaturalhistorian.com/2016/03/30/the-great-genetic-bottleneck-that-contradicts-ken-hams-radical-accelerated-diversification-ie-post-flood-hyper-evolution/

Scholars also state that the survivors would experience a founder effect. This happens when a very small group becomes isolated and reproduces only with each other. It means all the survivors are closely related to each other.

Some scholars propose that the flood narrative comes from a more localized event, like the Black Sea deluge, and describes a founder effect among one population of humans.

 Geology 
Geologists have found traces of severe floodings in remote history that were catastrophic, but limited to certain areas (not worldwide like the Genesis myth says).

The oldest geological evidence comes from the Channeled Scablands in the southeastern areas of the state of Washington. They were formed by a series of catastrophic floodsNeuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) Glossary of Geology (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp.  caused by the collapse of glacial dams in the area's glacial lakes. The last of these floods happened between 18,200 and 14,000 years ago, according to estimates.Balbas, A.M., Barth, A.M., Clark, P.U., Clark, J., Caffee, M., O'Connor, J., Baker, V.R., Konrad, K. and Bjornstad, B., 2017. 10Be dating of late Pleistocene megafloods and Cordilleran Ice Sheet retreat in the northwestern United States. Geology, 45(7), pp. 583-586.

There was massive flooding along the Katun River (in the present-day Altai Republic) some time between 12000 BC and 9000 BC, according to geologists.Baker, V. R., G. Benito, A. N. Rudoy, Paleohydrology of late Pleistocene Superflooding, Altay Mountains, Siberia, Science, 1993, Vol. 259, pp. 348-352Rudoy A.N.

Like with the Channeled Scablands, the collapse of dams in glacial lakes caused outburst floods from the Altai Mountains. Evidence comes from much of the gravel deposited along the Katun Valley. It is not arranged in clear layers, which suggests it was dropped from fast-moving water.

Another geologic feature believed to have been formed by massive catastrophic flooding is the Tsangpo Gorge in Tibet.Montgomery DR."Biblical-Type Floods Are Real, and They're Absolutely Enormous."

"Historic Himalayan Ice Dams Created Huge Lakes, Mammoth Floods." Science News, 2004 December 27. https://www.sciencedaily.com/releases/2004/12/041220010147.htm As with the Channeled Scablands, breakthroughs of glacial ice dams probably unleashed massive and sudden torrents of water to form the gorge some time between 600 and 900 AD.

 Archaeology 
In 2020, archaeologists discovered evidence that a 16-meter-high tsunami hit modern-day Tel Dor, Israel, during the Neolithic period. It traveled between 1.5 to 3.5 km inland, destroying middle Pre-Pottery Neolithic B coastal settlements. Recovery in the affected areas was slow but overall, it did not significantly affect the social development of the southern Levant. 

Whilst the tsunami is not identified with the Biblical flood, it is believed to contribute to the flood myths found in numerous cultures.
