Dear skumar ,I know that purposefully you are trying to poke but remember skumar everybody knows who the father of Rama is.And understand one thing the mythology of Hindus dates back when proofs of science were not discovered and not recorded .the yogic power where people ,sages and religious heads were using cannot be explained until you experience it.If something is said in scriptures ,it has some basis which is relevant to the conditions and the capacities of those times.If history says Dinosaurs existed and they were huge ,its difficult to believe in these times ,as we cannot estimate and believe that they are so huge.Similarly,if you have read miracles, unbelievable things happened in Hindu scriptures ,its not simply for the sake is written, but it is beyond you believe that in those days many such things might have happened.
