Some people believe that Jainism even existed much before Hinduism and Buddhism. Jains believe that Jainism is an eternal religion. Recent researches by some historians even show that Jainism might have even existed 5 lakh years back. If this is believed to be true, then it is quite possible that both Buddhism and Jainism were actually branches of Jainism, where Buddhism is quite similar to Jainism in many respects. Moreover, Hinduism might have been a mixture of local and some Jain beliefs.
