In this episode of Stuff You Should Know, the hosts explore the widespread occurrence of flood myths across different cultures worldwide. They examine notable examples, including the biblical story of Noah's flood and the Epic of Gilgamesh, discussing how these narratives share common themes of survival, divine intervention, and civilization's renewal despite originating from different regions and time periods.
The hosts delve into various theories that might explain these parallel flood stories, from the spread of Proto-Indo-European cultures to the influence of Christian missionaries. They also examine how geomythologists connect these ancient narratives to actual geological events, such as the Mediterranean's breach of the Bosporus Strait and the formation of the Persian Gulf, showing how myths often preserve memories of historical events.

The story of Noah's flood isn't unique - it shares remarkable similarities with flood narratives from cultures worldwide. The Epic of Gilgamesh, discovered by Assyriologist George Smith, contains a flood story that predates the Old Testament by several hundred years. In this version, the god Enlil instructs Utnapishtim to build a boat because humans were too noisy, rather than too wicked as in the biblical account.
A study identified flood myths in 50 different cultures, from Chinese mythology to Aboriginal Australian traditions. These stories often share themes of survival, divine intervention, and civilization's renewal after catastrophic floods.
Chuck Bryant and Josh Clark explore several theories behind these widespread flood narratives. The "localized flood" theory suggests that ancient regional floods were exaggerated into global narratives over time, particularly as Proto-Indo-Europeans spread throughout Europe.
Another theory points to Christian missionaries' influence during colonization. For instance, the Maori people had no flood myth before missionary contact in 1814, but afterward developed one resembling Noah's story. However, Clark notes that some flood myth similarities existed independently of missionary influence.
Geomythologists study how myths might represent actual geological events. One compelling example links the Mediterranean's breach of the Bosporus Strait 7,000 years ago to both Gilgamesh's and Noah's flood narratives. According to oceanographers William Ryan and Walter Pittman, this event created a waterfall 200 times larger than Niagara Falls.
Other geological events, like the Persian Gulf's formation 7,500 years ago and Doggerland's submergence, may have inspired regional flood myths. A 2016 study even found geological evidence supporting China's Emperor Yu flood myth, demonstrating how ancient narratives often preserve memories of real historical events.
1-Page Summary
Discussions on the parallels between Noah's biblical flood in the Old Testament and ancient flood narratives reveal the commonality and significance of these tales across different cultures.
The Epic of Gilgamesh, acknowledged as the first literary work, includes a flood narrative that closely resembles the story of Noah's flood. Assyriologist George Smith discovered the story within the text of Gilgamesh during his research. This narrative, which dates back 3400 years, predates the Old Testament by several hundred years, suggesting that the Noah story could have been adapted from the older Mesopotamian text. In the Epic of Gilgamesh, Utnapishtim is instructed by the god Enlil to build a boat to save himself from a flood sent because humans were too noisy, contrasting with the biblical reason that humans were too wicked.
Flood myths are not unique to the Mesopotamian region or the Abrahamic religions. In fact, a study cited in the discussion identified 50 different cultures with their own flood myths, indicating a widespread occurrence of flood narratives. These stories span cultures across the globe, including Chinese, southern Canadian, and British Isles societies.
For example, in Chines ...
Noah's Flood and Other Ancient Flood Myths Parallels
Chuck Bryant and Josh Clark explore the origins of widespread flood myths in various cultures, examining different theories that attempt to explain the prevalence of these tales.
Bryant and Clark delve into the "localized flood" theory, which suggests that ancient regional floods may have been exaggerated into narratives of global floods. These stories, affected by cultural transmission and transformation over generations, could explain the similarities between flood myths across different societies.
The Proto-Indo-Europeans are pinpointed as one group that may have experienced a flood. As they spread throughout Europe, their descendants, who spoke languages such as English and Germanic, carried the mythology with them, implying that this localized event had a global impact.
Supporting this theory is the idea that cultures without a flood myth simply may not have experienced a local flood, or it was not significant enough to be immortalized into their oral traditions.
Bryant and Clark also discuss the role of Christian missionaries during the colonization period. It is theorized that the story of Noah's great flood from Judeo-Christian theology was introduced to local cultures across the world and led to the adaptation of existing myths or the creation of new ones that mirrored this narrative.
A key example is seen in the Maori flood myth from the South Pacific, which did not exist before contact with Christian missionaries in 1814. After this encounter, a flood myth emerged within the culture, showing remarkable similarities to the story of Noah.
Josh Clark adds that even if missionaries spread the story of Noah's flood, some similarities in flood myths exist outside of this context. Post-contact, flood myths in the South Pacific that were originally based on tsunamis transformed to resemble Noah's flood, with narratives featuring prolonged rain and a more significant deluge.
Theories Explaining Flood Myths in Different Cultures
Geomythology explores how mythological narratives, like flood myths, may actually represent real geological events while also serving as culturally and metaphorically rich stories.
Chuck Bryant speaks about the correlation between myths and geological events, suggesting the study of geomythology uncovers the historicity within these myths. Geomythologists, who are trained geologists, work with experts from various fields to find the real-life events behind these tales.
Geomythologists suggest that legends and folklore hold eyewitness accounts of natural disasters, encoded with metaphorical language to describe events like volcanic eruptions. One example is the legend of a god spouting fire from a volcano as a metaphorical warning of a volcanic eruption. Geomythologists rely on methods from paleohydrology and paleobathymetry to align geological evidence with such myths.
There is a hypothesis that suggests the Mediterranean's breach of the Bosporus Strait approximately 7,000 years ago could be the historical event underpinning the flood narratives in the Epic of Gilgamesh and Noah's biblical account. The resultant flood, which would have felt like a global catastrophe, generated a waterfall with a volume 200 times that of Niagara Falls and is a probable source for these ancient deluge stories.
Oceanographers William Ryan and Walter Pittman's theory posits that the massive flood from this breaching event could have inspired various flood myths due to the sheer scale of the waterfall and the catastrophic inundation it caused.
In other instances, the creation of the Persian Gulf around 7,500 years ago from what was once a fertile river valley, now a large body of water, and Doggerland's flooding, possibly from the Storegga Slide, are seen as geographical events t ...
