Jimmy Corsetti is the owner of the YouTube channel Bright Insight which deals with a range of what is considered ‘fringe’ subjects. Over the past few years, he has been advocating the Richat Structure as the remains of Atlantis, despite a total lack of archaeological evidence and so much scientific support for its identification as a ‘salt dome‘.
Corsetti was overjoyed and felt vindicated when David Edwards published Atlantis Solved  in April 2022 which also endorsed the Richat Structure as Atlantis. However, Edwards admits that he has built his claim on Corsetti’s earlier ideas regarding Richat and is only offering an echo.
David Edwards is the author of Atlantis Solved: The Final Definitive Proof , a slender 99-page volume published in 2022 that endeavours to prove that the Richat Structure was the location of Atlantis. The author claims to have been inspired by videos by Jimmy Corsetti, on the Bright Insight YouTube channel, who has been promoting the Structure as Atlantis for the past four years.
This identification has no archaeological or geological evidence to support it and more importantly, it conflicts with Plato’s account. These shortcomings are dealt with in greater detail in the Richat Structure entry here.
