Australians To or From Göbekli Tepe?

Bruce Fenton has considered the roots of human civilisation are somewhere around between Australia and New Guinea or so.

In other words, just after Younger Dryas, or at end of it, people got from Australia (or therearounds) to Anatolia.

His argument is, there are similarities between art found at GT and art found on Arnhem land - after seeing this video, I agree the similarities are huge:

Actually, they are not limited to Australia, but on my view include Polynesia (the heads of certain birds recall Polynesian birdmen) and Mexico (the eagle with a serpent).

There is another direction which is possible : Arnhem land "35 000 BP" in carbon dates was a first post-Flood settlement, but part of the art is actually later, and comes since some of the men at Babel left ... Göbekli Tepe ... on the way to join their relatives./HGL
