To learn and understand the epics, vedas, puranas etc. of Hinduism,even a life span is not enough. The other religions where all beleifs are based on single rewritten books, they have enough time to find falt with others. They have first to learn the scholarly books that clearly writes with ample proof that Christ escaped from crucification and lived in India as a Hindu and that in the Kaa.aba they really worship the Shiva Linga'. As the Christainity is fast declining in the West, they will soon start learning Holy Gita.
