For a long time, I heard and learned that the Aryans came and conquered India around 1500 BC. Somehow, that never made any sense to me. I always wondered that if that was the case, did Ramayana and Mahabharata ever take place in India? I have been reading those sacred texts ever since I can remember and my curious mind always wanted to know the truth.
Finally Ajit, my brother-in-law, sent me a link about a research on this.
Google video about Vedic Intelligence
Having been to many of these cities myself, I always believed that somehow there was some fact in the Vedas. I think, somehow, this research tells me that things really happened as described in the Vedas.
