FRiend Sunken Civ, the Aryan Invasion theory has now been discredited as it sems to have little basis in history and antiquity.
The hypothesis that the Sarasvati (Indus) Valley civilization is a Dravidian one is also suspect and is put forth by charlatans like Iravatham Mahadevan (who i also mentioned in your excerpt).
How are you?
The Aryan invasion is factual, and has been rejected for nationalists. The Aryans came out of Central Asia, more than once, and not just into India.
And oh yeah, BTW, where have *you* been? I hear from you maybe every two months around here.
