I'm about to cast the fifth reopen vote, so I might as well give my thoughts on the question.
The first version of the question was
Is Diana themeskara real?if so is Atlantis real?
Does anyone have any real proof not from comics or movies
When I see that, I think of someone asking if these things are - well, real objects in our world. It reads like someone asking if Bigfoot is real - especially as the reference to "comics or movies" seemed to suggest that the OP dismissed those as being fictional representations. So at first glance, it looks nothing like a question about mythology.
However, I wasn't sure that that's what the question was actually asking. I was extrapolating. When in a situation like this, I'd vote to close as Unclear What You're Asking, so I waited (not wanting to mod-hammer it) and then cast the fifth close vote (the second version, after an edit, was no clearer, though still helpful).
After that, several edits (mostly by yourself) made the question much clearer. I don't know if this is what the author intended, and I'm wary of changing the intent of a question like this. However, the author deleted their account, and the question in its current form is both clear and on-topic:
How is Wonder Woman related to the Amazons of Greek Mythology and Atlantis?
Does anyone have any real proof not from comics or movies that Diana of Themyscira is an actual figure from mythology? How does Atlantis relate to this?
For background, Diana of Themyscira is name of the modern superhero, Wonder Woman. In the comic books, Themyscira is the capital of the Amazons, and depicted as a mysterious island with a hidden location, similar to Atlantis.
You can't get much clearer than that. Question reopened.
