when sumerians ran away from babylonian invaders a fair amount found refuge with dravidians. dravidians and sumerians afterwards shared a common language.<quoted text>
Have you read the work of linguist Susunu Ohno? he believed there is strong linguistic evidence that Japanese and Korean is closely realted to Tamil (Indian). Indeed one Indian person I know who speaks Japanese tells me there are hundreds of words in common between Japanese and Tamil.
Perhaps people in Japan and Korea are embarrased that dark skinned indians could have taught them culture and language?
sumerians owed a debt of gratitude towards dravidians for taking them in.
