Look up 4000 years ago, India, and the interesting (though IMO not feasible) claim that the Indus Valley Civilisation is the "mother culture of all the Indo-Europeans".

This is an idea I have seen before, and is mooted by a number of Indian and Pakistani historians, but I'm sorry, I don't yet buy it. The dates alone seem wrong, as well as the technology: it's all very well for them to have had iron at the time, but what about horses and chariots?

Interesting idea, though.
