"While I won't say specifically 6,000 on the nose, I will say that I believe that the events of Genesis happened within thousands or tens of thousands of years and that Hinduism is a later derivative of fertile crescent polytheism.
There are two broad views of religion: that monotheism was the original faith with polytheism being a "de"-volution of this original faith...and that animistic polytheism was the original faith and that monotheism is an evolution of it. Clearly, I believe the former to be the case."
In recent history, it's been monotheism that has replaced polytheism. Knowing a few Hindu people, I wonder how long it will last as a faith instead of a few ancient cultural rituals. It seems as if it has a Greco-Roman feel of antiquity to it, at least to first and second generation immigrants.
