During the Ice Age in the days following the Tower of Babel, progeny of Kush such as Rama moved eastward from cities such as Kish in Mesopotamia to where today is called Khuzestan, some on their way far to the east and south (some by sea) to where ice age Kushasthali was built (now submerged) of the Indus Valley Civilization. During the Ice Age, the Persian Gulf was dry land with the Shatt al Arab river running through it, thus surely the ruins found on the seafloor are of Kushites and Elamites too.
