Progeny of Kush (a son of Ham and grandson of Noah) moved east and south from Mesopotamia after the confusion of language at the Tower of Babel, some then migrated to where was founded the ice age Indus Valley Civilization with its “undeciphered” script of pictograms, but the submerged city of Kush, Kushasthali (on the seafloor of the Gulf of Kutch), means Kush’s thalassocracy, an indo european (japhetic) word for sea power, proving that though perhaps mostly Hamitic the Indus Valley people adopted a language (Sanskrit) of Japheth’s progeny not Ham’s.
