[Mr. K]

there are many recent finds of houses and cities under 10-20 meters of water

These are ANCIENT cities and must be from a very long time ago when sea levels where that much lower

if you look at the Atlentic ocean, it alwasy seemed odd to me that the Atlantic Shelf went out so far and then suddenly dropped off... It looked like the sea level was at that point for a long long time and then rose ... 20 meters

Giving us our current shoreline

As recently as 400 years ago, Venice was on a peninsula and hub of a great empire.

Today, Venice is a city in northeastern Italy sited on a group of 118 small islands separated by canals and linked by bridges to the mainland and each other.
