YouTube channel 'discovers lost city of Atlantis' - buried in middle of the Sahara desert
The lost city of Atlantis has long been a mystery - but now conspiracy theorists are claiming they have found the mythical island.
And it's apparently been in right in front of us this entire time.
The story of Atlantis comes from the Greek philosopher, Plato, whose books date back to approximately 360 BC.
According to the story, which has now become somewhat legend, the island of Atlantis sank into the sea in a single day and night, lost forever, after its people fell out favour with the gods.
Conspiracy theorists have long been searching for the location of mythical city, with guesses ranging from Santorini, Sicily and Malta to Crete and Cyprus.
But now, YouTube channel Bright Insight claims to have discovered a location in the Sahara Desert in Africa that has similarities to the details written about Atlantis all those thousands of years ago.
The Richat Structure, which is also know as the Eye of the Sahara, located in Ouadane in west-central Mauritania.
The bizarre, circular feature was thought to have been created by an asteroid, although no credible evidence actually exists to prove this is true.
Scientists have since concluded that the structure must be a natural phenomenon.
But this is not necessarily as cut and dried as it seems if Bright Insight's theories are to be believed.
Plato stated in his texts that Atlantis was destroued in 11600 BC, which fits with the timing of The Younger Dryas theory that suggests a comet is said to have the hit the Earth and caused the Ice Age. Could that have been how Atlantis was destroyed?
But the coincidences don't end there.
According to the channel, the Richat Structure has a outer circle diameter of 23.5km, according to Google maps.
In Plato's writing, the city of Atlantis was said to measure 127 Stadia, which would equal 23.49km in today's terms.
Plato also described Atlantis in his texts, writing: "There were alternate zones of sea and land encircling each other, there were two of land and three of water."
This description is very similar to what the Richat Structure looks like, when viewed from satellite, today.
Add to that Plato's description of a mountain range to the north of the city and an oblong-shaped plain to the south - which appear to match the topography surrounding the structure in the Sahara - and it seems that the two share a certain likeness.
Of course, Plato wasn't actually alive at the time Atlantis was destroyed. Instead, the story was passed to him by Solon, a statesmen from Ancient Greece.
Viewers on YouTube were divided, with Karolina B. writing: "Wow. Too many coincidences. I don't usually take videos on subjects like this and instantly believe them but this... this is too convincing."
Others, however, remained much more cynical. 'Vigo' wrote: I'm extremely sceptical about this. The arguments which you give are pretty convincing on their own, but it still lacks one thin: evidence. Most of your points can be explained away be coincidence."
