What are you babbling about? This guy is a respected Jewish professor of History. It has been proved that Aryan invasion theory is false and it is actually Indians who migrated to west and gave them civilisation.
British Druids were the Brahmins of Celtic society and were considered descendents of Indians. (Drav -- liquid, Vid -- Knowledge). Druid means immersed in knowledge. This designatin still survives in INdia in "Dravid," the same word from where the name David is derived. Google Brahmins and Druids.
