Actually, we have a lot of evidence from civilizations that the levels rose gradually.

What if Atlantis was not an Island, but the entire world. An ancient world during the Ice Age when sea-levels were lower, when the Sahara was
a vast grass land with huge rivers?

It's a great fantasy, truly, and would make a wonderful fantasy story. But Atlantis is a fantasy (there's no evidence for it).
Let me tell you a bit about human history... the parts they gloss over unless you're taking this in depth in college.

Imagine a world of trade; one common language; and though maybe not technology comprable today, certainly more than the ancient world shortly
after.

Actually, this did exist with our Australopithecene ancestors in Africa. As Australopithecene evolved toward Homo erectus (our immediate ancestor) we
find things like "factories" where specialized tools were made. We see a lot of things that talk about the origingal cultures such as the shapes of
stone axes (and of course the Clovis spearpoints.)

A world completely drowned in a deluge with the end of the Ice Age; over-crowding leads to war and the end of civilization. People return to
tribalistic savages.

The human lineage has survived several ice ages in its long history. Remember that humans until fairly recently (9,000 years ago or so) were nomadic.
Sea level rise, humans move.

Language barriers are created once more.

Language divergence began more than a hundred thousand years ago (we know this by the patterns of language and by other evidence. Language isn't a
dead thing but constantly evolves, so we have a continual stream of new languages being formed. For instance, someone from Liverpool today might not
be able to understand an American Black from the inner city of Detroit.

Plato put the age of Atlantis' destruction at 9,000 years before his time. This is at the end of the Ice Age.

Eh... not entirely. It didn't just "shoop" end. Important warming trends began only 7,000 years ago.

Plato said it was a continent beyond the pilars of Herakles.
Perhaps when he was saying it was as large as Africa and Asia he meant it spanned across these lands.

It was as much a fantasy as Narnia is.
Greeks loved plays and they loved tragedies and they loved art. The evidence for Troy came from plays, odes, songs, sculptures of Trojan heroes...
and so forth. Trojan heroes were painted on jars, and the name Troy and Trojan War shows up all over the place.
There is no play about Atlantis (there should have been dozens), no legends of Atlantean heroes, no sculptures of "so and so of Atlantis", no
paintings of them, no legendary names... nothing.
The lack of any other mention of it and lack of drawings and lack of legends is exactly what we'd expect if Plato made it up completely and didn't
use any stories as basis of his tale. There are no Atlantis type myths in Egyptian mythology (I'm pretty familiar with most of the Egyptian
tales.)

But around the world, we constantly find ruins in the sea...is there a coordinated effort to correlate the ages of these ruins?

Oh yes, they're dated by the archaeologists. There's a Harrapan city that dates to 6,000 BC in India and other sites around the world. Here in
Texas, we have coastal villages of Amerinds (temporary camps) that date even older than that, and there is an investigation of a site in North
Carolina that has been submerged by the rising ocean levels -- a site believed to be nearly 20,000 years old.
