It was interesting to watch the video "Atheism Defeated" recently. (Please watch the above short video before reading my comments below).
However, Hinduism and Christianity are poles apart. Hindus believe in the Vedas but these do not claim to be the inerrant word of any gods. Hindus also hold that the Bhagavad Gita is a holy book, but as god in Hinduism is not personal it cannot be the revelation of a personal god - so why should we accept it or listen to what it says? Hindus do not believe in certain knowledge or absolute truth, but believe that everything is illusion (maya). As the maker of this video isn't a Hindu there isn't much point going too deep into this - I'm just pointing out that once again an attempt to refute the biblical God falls apart on closer inspection.
