it's actually thought that most of the mega flood myths, being centered in europe, india and the middle east, came from the fact that the Mesopotemian civilisation was built around 2 rivers, The Tigris and The Euphretes, these two rivers have a history of violently and unexpectedly chaning course. So some cities back then would cease to exist as the river that was next to it was now running miles away and often cause major flooding. Humans have a tendency to turn regular cataclysms and up scale them into apocalypses, earthquakes, volcanoes, tsunamis, disease, meteors, ect. So a civilisation plagued by farmland being flooded or drying up due to violent changes in the rivers that gave them life would in all likelyhood make a concept like a world ending flood.

The Black Sea also filled up brutally, when the Bosphorus "plug" collapsed. But contrary to the Mediterranean flood, which happened 5.33 million years ago, with no human to observe it (NO, it was NOT the biggest flood ever seen by humanity!!!) , the Black Sea flood happened ca. 7600 years ago... and flooded human fields, human habitat under tens if not hundreds of meters of water within days and weeks... (40 days maybe?😉). That event certainly traumatized those tribes... and are maybe... just maybe... the source of the Noah's Flood story! At least, it is geographically pretty much in the right place! Also, the episode during which the Mediterranean Sea was cut out from the ocean didn't last long in geological times... not millions of years, but a mere 550'000 years, roughly. It also didn't happen once, during these 550'000 years, but many times, with the sea filling, then the Gibraltar Straight closing again, then rupturing again, perhaps only partially, etc. Proof of that is the thickness of the salt deposits mentioned in the video. They just cannot have been created by the sea evaporating a single time! Tomas, it might also be worth talking of Messinian canyons (like the ones underneath Cairo, Lyon, ...) or of Messinian lakes like Laggo Maggiore.

This is probably the best explanation of how the Mediterranean Sea flooded. It kept my attention from start to finish!

No way THAT super flood from 6 million years ago would be part of the human folklore of a biblical flood. in order to be part of any cultural history it would have to be much later. Homo Sapiens didn't even exist yet, heck, Neanderthals didn't even exist yet (they only appeared 200 thousand years ago in the Pleistocene Epoch). Any event that happened 6 million years ago would not be part of any remotely human recollection. The biblical flood was opined to be about 10 thousand years ago with a meteorite or comet hitting the Atlantic ocean (i think). That's why an apocalyptic flood is part of so many ancient civilizations verbal histories.

The river canyons on the upper continental shelves formed from extension of existing rivers during glacial periods, when sea level was much lower and a much larger area of the shelf was exposed to erosion than today. Example: ("inner") Hudson Canyon, south of New York/Long Island, which is river-carved into the upper shelf. Below the continental "shelf break", as the shelf gives way to the deeper (and steeper) continental slope, the channels are carved by turbidity currents, which are episodic undersea "avalanches" of sediment mixed with seawater. They are denser than normal seawater and so flow with the slope topography and erode progressively deeper channels as they recur ("outer" Hudson Canyon, cutting into the shelf break, is again an example). Then they reach the (deeper, less steep) continental rise, spread out, and the sediment settles out. Farther out on the abyssal plain, visible features include abyssal hills (seamounts) and linear, parallel transform faults, the latter from tectonic seafloor spreading.

Hahaha first time I hear that comparison with Pedro Pascal. What an honor!

You are mistaken about undersea river canyons. The Monterey undersea canyon is the ancient river mouth of the Salinas river which drained all of central California prior to the current outflow out the Golden Gates. If you look off the coast of California, you will see a series of small underwater canyons all along the coast. The flat plain just off the cost defines the ancient coastline during the low stands of sea level caused by major ice ages. When sea level rises, the waves quickly clean the top of the plain. They then start eroding into the rising coastal mountain range as is happening today. The underwater flat plain north of the Bosporus Strait ringed by underwater canyons could be a similar evolution. This might imply that the Black Sea has held water during the time the Mediterranean was dry. Its water source could be eastern European rivers, the Danube, Dniester, Dnieper and Don rivers. These rivers would have reduced flows during ice ages leading to lower Black Sea levels. Hence the underwater flat plain around the Black Sea. But this is a guess on my part. My geology knowledge is from 45 years ago and the science has evolved since then. Great video BTW. Thank you.

Thank you. But river channels can easily form on seafloor, and even ocean floor, like the great channels by the Indus and Ganges on the bottom of the Indian Ocean. That ocean was not dry. It is done by the grains of sand and silt in the river water, which when empties by the river into the sea, they drops down to the bottom of the sea and keep going toward to the deeper and deeper places in the ocean or sea. In the process, those grains gradually dig a channel at the sea bottom. I am not saying the ones in the Mediterraneans are necessarily made that way, but rivers do cut canions/channels on the sea floors

@@sgwa11 Most if not all, are naturally made that way on the seafloor. So to prove they were dryland when the rivers flowed, they need to drill into the sediment and find naturally growing roots of plants (not just burried plants, because they can be just washed in from the dry land and get burried there). None has been done to the best of my knowledge. But for the Mediterranean, the miles high salt deposits at the bottom of it is the BEST reason for that sea having dried up, dozens and dozens of times, not just once, leaving behind all the salt, then flooding, then drying up and more salt... on and on! The Black Sea and the Caspian often connected through the Manich depression, and they shared water. The Marmara barrier was actully broken up by earthquakes and the southwest movement of the Anatolian microplate. Even today, the Black Sea has two distinct layers: salty at the bottom, nearly fresh water on the top.

somewhere on you tube there is a video of some one digging a one spade channel between a rive and the sea, within 15 mins it is a raging torrent. this is a good example at the power of water causing erosion,

Outstanding explanation. Enjoyed it.

Interesting to mention is the Panonian sea in Europe (Today's Hungary, Serbia, Croatia) It disappeared around a million years ago, but I'm not sure. Did it flow away into the Black sea? Did it just dry up?

The formation of submarine canyons occurs as the result of at least two main processes: 1) erosion by turbidity current erosion; and 2) slumping and mass wasting of the continental slope. While at first glance the erosion patterns of submarine canyons may appear to mimic those of river-canyons on land, several markedly different processes have been found to take place at the soil/water interface. What you are referring to as "river channels" are not formed by rivers but by submarine currents. You can see these in all different parts of the world on each and every continental slope, and do not necessarily mean a mega flood. However, the way you describe the Zanclean Flood event is somewhat correct, and is a very active field of research, however the I would like to note that during the Messinian Salinity Crisis the Mediterranean was partially dry and not completely dried up as it was thought previously. Overall nice job!
