"Yes and no - depending on which account of history you accept, Hinduism post-dates the events of Genesis making the Judeo-Christian tradition the oldest religion on the planet."
Yes, well. Are you a believer that the events of Genesis happened around 6000 years ago? If so, then you have a point.
Either way, Hinduism is one of the great religions of this planet. Its history and beliefs are not for ridicule. Anyone who ridicules Hinduism mocks his own beliefs, as well, in my opinion.
Wrong. The Vedas were written in 15000 BC long before Genesis and birth of Judiasm.
