Thus, it is likely that Atlantis is a non-fictional story.
The most concrete proof of Thera being the lost empire in this story, lies in the consistency of the dates and figures. Moreover, a comparison between Plato's statistics on Atlantis, and the known facts of Thera, can only result in one conclusion - that Thera is what Plato was writing about.
