Ive been wondering the same thing for the past year or so. hell they could just change the name to “The Discovery Channel”.
One of the items on the list is the Lost City of Helike. That is less mysterious than some of the others--its destruction can be dated to 373 B.C.
Plato's myth of Atlantis appears in two of his dialogues, the Timaeus and the Critias, which appear to be among his later works, probably later than the Republic. It's hard to determine when any of Plato's works was written but a date around 374 seems to be favored by some scholars for the Republic, so Plato could be writing about Atlantis after the destruction of Helike.
