An on-again, off-again theory suggests they found Atlantis decades ago, in an unlikely place. There’s no solid evidence it was Atlantis, but a YouTube video presents a pretty persuasive set of coincidences. Still, the video contains a lot of supposition and only glosses over alternate views from archaeologists who’ve explored the region (no “army” of archaeologists have explored it, but there have been a few expeditions since NASA astronauts discovered it around fifty years ago).

From Newshub:

According to a YouTube clip uploaded earlier this week that’s found a massive audience online, the remains of the ringed city Plato spoke of in the fourth century BC can be found in the African country of Mauritania.

And it’s been hiding in plain sight this whole time.

“We’ve been looking in all the wrong places for its location since everyone assumes it must be under the ocean somewhere, such as in the depths of the Atlantic Ocean or the Mediterranean Sea,” says the host of Bright Insight YouTube channel, known only as Jimmy.

Instead he proposes a strange formation known as the Richat strucuture, or the ‘Eye of the Sahara’, is the mythical city’s true location.

He says it is not only the exact size and shape Plato said it was – 23.5km across and circular – but mountains he described to the north can be seen quite clearly on satellite imagery, as can evidence of ancient rivers, which Plato said flowed around the city.

Here’s the YouTube video in question. It’s worth a watch, because the similarities are numerous and persuasive; but take it with a grain of salt.
