What Is The Oldest Religion Still In Practice Today?

Hinduism and Judaism slug it out, both are between 5 and 6 thousand years old. In evidential terms, I'd give it to Hinduism, as there's little or no record of Judaism more than 4,000 years ago, even though they claim it to be year 5769 of their calendar. They also claim that Methuselah lived to be more than 600 years old, so maybe they had a different view of 'years' in the old days..........
