Radek Brychta is a Czech writer who has written about the transmission of the Atlantis story from the Indus civilisation city of Dholavira, which he claims was the legendary island of Dilmun recorded by the Sumerians and from them, transferred to Egypt and eventually related to Solon.
John Sassoon has suggested, based on Genesis 11.2 that the Sumerians had in fact migrated from the east with the Indus Valley as a possible point of origin. He suggests further that the Sumerians were in fact the progenitors of the Jews. This theory would also offer a line of transmission from the Indus valley to the Nile delta.
An abbreviated version of Brychta’s book in seven sections(a) with an extensive bibliography(b) is available on the internet and is worth a read.
He includes a rational explanation for the 9,000 year age of Atlantis by noting that the Egyptians, as well as the Indus civilisation, counted time in seasons of which there were three annually. Dividing 9,000 by three and adding the probable date of Solon’s Egyptian sojourn, 590 BC, gives us a more credible date of 3590 BC. This idea has also been proposed by Rosario Vieni.
A further possible link between the Atlantis story and the Indus civilisation is strengthened by such matters as the existence of elephants.
