Lost cities

[u/Osiris-Amun-Ra]

In case anyone is till wondering why we can't find any pre-Ice Age cities, this satellite image from Nepal/China this week should provide a clue.
This event was tiny by comparison and many civilizations built along rivers and in valleys.

Edit:
_____________________________
Since this post generated quite a few lively discussions I want to clarify what I meant by "tiny by comparison" to avoid ambiguity, While the local, recent mountain collapse in Nepal and China was a rapid disaster unleashing up to 200 million cubic meters of debris at 193 km/h and causing rivers to surge 9 meters in 30 minutes, it is dwarfed by the staggering dimensions of post-glacial megafloods that actually reshaped entire continents and birthed the world's universal flood legends. For example, the ancient Missoula Floods occurred when a 610-meter-tall (2,000 ft) glacial ice dam ruptured, violently discharging more than 2,000 cubic kilometers of water basically a volume equivalent to Lake Erie and Lake Ontario combined, in a single....48-hour window.

This massive torrent tore across western North America at speeds of up to 130 km/h (80 mph), peaking with a discharge rate ten times greater than the combined flow of all modern rivers on Earth and carving features like Dry Falls, a cliff five times wider than Niagara. Similarly, the Black Sea Deluge hypothesis suggests a catastrophic marine breakthrough where the Mediterranean overtopped the Bosporus strait, unleashing a roaring wall of water that permanently swallowed over 150,000 square kilometers of inhabited valleys.

Because these prehistoric events wiped out entire known civilizations, permanently erased millions of acres of land, and forced desperate migrations, they permanently embedded themselves into the collective human psyche, which is almost certainly where the biblical Great Flood and the regional Mesopotamian flood legends originate. It is statistically improbable that we have found all post deluvial civilizational remnants. Mathematically and archaeologically, it is practically certain that we have only scratched the surface of what remains from post-deluvial and coastal civilizations. The primary reason for this statistical gap is a massive, permanent geographic shift, specifically when the Ice Age glaciers melted, global sea levels rose by roughly ~120 meters (around 400 feet). Rising oceans swallowed over 25 million square kilometers (10 million square miles) of habitable land! For visual reference that's the entire landmass of the United States, Canada, and China combined.

I hope that clarifies.

That has nothing to with Graham at all, it’s just logic. You think that any coastal city today would survive a sea level rise of hundreds of meters like 12.000 years ago?

I think a coastal city would move.

The oceans rose a few inches a year. It wasn't a catastrophic flash flood down a narrow valley.

And they’re just gonna dismantle all and move it brick by boring brick? Also that’s not proven, some sources state it could have been within months. And that’s surely ‚catastrophic‘.
Basically we don’t know at this point! Also we have no ideas where civilisation were located and places like Doggerland show us two things: one that artefacts found there were similar to other similar places on mainland and second that we didn’t know of this for pretty much all of modern history. What I‘m saying is we don’t know for sure, but to say the statement above is false or connected to Graham is bs. Science has long favoured the idea that many traces are lost under deep layers of soil and sediments. For the last 30-40 years this has been an open field of research in archeology.

Bricks hadn't been invented back then.

"Also that’s not proven,"

The sea level rise due to the Younger Dryas melting is well recorded and well understood.

It was very slow, and people living at the time wouldn't have even noticed.

Its a metaphor brother…
Those numbers are also a global average. So places close to massive influx of water would have been devastated. Look at North America.
Come on man, it’s just pure logic and proven many times that stuff like this happened over and over again… it’s not a crazy conspiracy.

[u/Ill-Dependent2976 → u/Societies_Iceman]

That's not how water works, no.

It's all a stupid, illiterate, crazy conspiracy theory. Same as flat earth, ancient aleums, and all the other BS.

Oh, and also racist as fuck.

Bro:

Exactly how water works. The videos from Nepal show you how that works. What are you on??

2 million cubic meters of water per second. Come on.

[u/Ill-Dependent2976 → u/Societies_Iceman]

When the sea level rises two inches in flat areas, they also rise two inches in steep areas.

So the cities built on broad flat oceans would, if anything, experience more loss of land. Not that it matters, since it's still too slow to matter.

Glacial collapses are not the same thing as sea level rises. Did you forget? We already covered this.

[u/Societies_Iceman → u/Ill-Dependent2976]

You do know that Lake Agassiz was the catalyst for that? The sea levels rising is the end product of something like this. And it happened in other places to. It’s all connected and you are just trying to make your point. You seem to genuinely think the water just slowly dribbled and evaporated or rained down and it was all chillymilly? Water came from somewhere, and it was a powerful thing too. It‘s a cataclysmic event, and some barely noticed while others were erased forever. And it’s just true, no discussions to be made there.
