Oil echo-sounding finds submerged land in North Atlantic that was once above sealevel

Am I missing something? The comments accompanying an intriguing article at Mail Online called Lost world: Ancient submerged landscape of mountains and riverbeds found on the Atlantic seabed seem to be deriding the information in the article.

The commenters appear to ridicule the author of the article for wondering if the underwater land that was once above sea level could have been the mythological land of Atlantis.

Is it the date? That the land has been submerged for 56 million years? Or is it because no ruins have been found (as yet) on this land? After 56 millions years underwater at the bottom of the North Atlantic, would buildings still exist?

I am amazed when one after another ruin above and below water around the Mediterranean, Caribbean, from Antarctica to Indonesia are hailed as the lost city of Atlantis that this . That’s not ridiculous?

For my part, I am excited to learn of this new discovery. Echo-sounding technique used for finding undersea oil made the unusual find.
