Quoting the artice '— but think that solving the mystery could lead to a huge change in how we understand early humans."

There is a city under water in the Gulf of Khambhat that's believed to be 9 and a half thousand years old. Amazingly beautiful decorated structure. There's a pyramid under water in the Azores that appears to be perfectly intact (including cap stone) that is around the same size as the great pyramid in Gaza. There's a hell of a lot under the water that is being (I believe deliberately) kept from us. Look up under water cities and structures.

These are but a few that have been discovered and you'd think they would make a big deal out of them in the media but 'nope'.

'How we understand humans' they say. The pyramids of Giza are how old? Psht!
