Japan language ping
While Europe may have been settled about 8,000 years ago, I is more likely that the waves of Kurgan invaders from the centeral Asian steppes around 6 and 5 thousand years ago brought the Indo-European languages. They also invaded India. In addition they brought the male killer god worship which displaced the female growing nurturing goddess worship. Thus a dominator social model may have displaced a more democratic partnership oriented social model, much to our subsequent distress.
