Are you suggesting the desert part of today’s Egypt wasn’t a desert during the Roman Empire?

No, that nation/boundaries may not be what they used to be.

Are you suggesting then that Florida’s boundaries were materially different in the early days of the USA than they are now? Aside from losing part of the panhandle, I don’t believe they have changed much since 1776 or that draining the swamps had anything to do with Florida’s borders

It was mostly worthless malarial swamp. The population of Miami was like 10,000 as late as 1900.

Now it is a paradise of sorts, but the foundation is unsound.

no, just that people didn't consider florida as a state beside palm beach, and now every inch of the land has been made worthy

Palm Beach was not founded until 1909, and Florida has some of the oldest cities in America, including “the oldest,” so I’m very curious to understand where your head is at on this one

Oldest continuously inhabited towns in US are pueblos in New Mexico and Arizona

It's not about cities but the global area.
