Did you know there are ruins of ancient and recent human civilizations underwater? They have a lot of nice loot apparently!
There are some interesting tidbits we can gleam about our past. Going further back, there is more we don't know than we do now about our origins. Ancient civilizations that have been lost to the sea is something really cool to learn about. There are many sites to look at.
Here are some notable locations:
Alexandria, Egypt
Time Period: 1,500 years ago
Earthquake and waves swallowed it into the sea


Thonis-Heracleion, Egypt
Time Period: 1200 years ago
Liquefaction of the silt foundation following earth tremors


Sunken Pirate City at Port Royal
Time Period: 1692
Earthquake swallowed it up into the sea

The Port Royal disaster was more recent compared to the others. But it demonstrates how any time period, recent or ancient, is not immune to the forces on this planet. Whether it be weather, storms, earthquakes of the melting of icebergs that has been ongoing for thousands of year, coastal regions are always at risk.
I wonder what other ancient civilizations existed on the coasts before and after the last ice age or flood narrative in our past? The water level was much lower then, and who knows what lies beneath the sea in some corners of the earth...
