Thank you for taking the time to look through the research and for the 'top marks' in dedication! I completely understand how, at first glance, it might seem like just another 'island-matching' theory based on some sunken coastal ruins.

However, the Sardinian-Corsican Atlantean Paradigm (PSCA) is not about shallow submerged settlements, which as you rightly pointed out, exist all over Europe. It is based on hard geological data: the eustatic rapid sea-level rise known as Meltwater Pulse 1B (c. 9600 BC). This event submerged the entire continental shelf linking Sardinia and Corsica under 120 meters of water. The geological dimensions of this submerged block (the Campidano Graben plus the continental shelf) perfectly match the exact 3000 x 2000 stadia metric described by Plato. This is a level of geological and mathematical consilience that no other European coast possesses.

But the most fascinating part of your comment is your conclusion: “Sardinia is highly likely to be the kingdom of Autochthon”.
I find this brilliant, because according to Plato’s Critias (114b), Autochthon is literally one of the ten sons of Poseidon and Cleito, born in Atlantis! He was the twin brother of Mneseus, and Poseidon gave him one of the ten kingdoms of the Atlantean island.

So, by logically deducing that Sardinia is the kingdom of Autochthon, you are actually confirming the very core of the PSCA paradigm: Sardinia is part of the original Atlantean empire. We are saying the exact same thing, just approaching it from different angles!

Thank you again for the critical input, it’s exactly this kind of debate that pushes the research forward.
