Atlantis was never described as a continent, but rather a city, and only one person originated the story. Plato said he dreamt of it. However, the idea of a city being sunk into the sea isn't terribly farfetched, and it has happened in the past. You are, however, seriously pushing the reality-meter when trying to apply this to a continent. And island, perhaps... but there's no sensible person with a background in geology that will back the sinking continent concept.
