It shows an image of something that looks artificial on the seabed off the Canary Islands. This is in the very location Plato said Atlantis was in his famous book. It certainly resembles a street plan; and it's huge, as big as Wales. This also matches Plato's description, of Atlantis being a massive city. Was Atlantis just a made-up story? The scientific establishment says yes, but I disagree. The myth of Atlantis exists in one form or another in nearly all cultures across the globe; including many who are supposed never to have had contact. It's the same basic story as Noah's Ark from the Book of Genesis, Manu in the Rig Veda from India, the Welsh legend of Cantref Y Gwaelod, and the Zulu folk tale of Zaralelli.
Sunken cities have been found before, most famously by Graham Hancock off the coast on India; see his brilliant book

But so far all these ruins have been in shallow littoral waters off the continental shelf, on seabeds that are known to have been above the sea level in the past. This new discovery is different; if it is real then it shows the presence of a city in the intercontinental ocean depths, the Madeira Abyssal Plain. There is no process known in conventional geology that can ever account for this part of the ocean bed ever being on land.
