Also, much like Atlantis which has been discovered (Richat Structure), many historians thought the great city of Nineveh to be just a myth. And then they found it. Alexander The Great looked everywhere for Nineveh. He literally marched his army right over it! Same with Troy. Just a myth. Now they have conclusive evidence they have found it.
There’s something down there....
