Rarely any one knows how language came into existence and ruled mankind for so long that exact era is impossible to say that when we started to use it. Mankind progressed and travelled from Stone Age to the era where human sneaked into space and stepped onto different planets which was not possible without language. Language is such a mightier tool that it described god who is a creator of everything. Is language created by who created everything (God) or human created language and written all the books through which we are trying to know the creator of all. If humans created language and praised god in language created by human that means either god is multilingual incase God is one, suppose god created language that means he understands different language and communicate in the language he is master of and we humans as a follower have to pray him in that language and that indicates god is not one and different as per faith and language.
As per above argument Gods existence is questionable and some group of people is trying to mislead major group of people with this tool, but then we cannot deny that on planet earth on which we live is round and floating in dark space with other infinite planets. So there is somebody or some kind of strength which is administering all this mechanism are we calling that mechanism god! It is getting complicated further we try to describe God so let us not go further and try to focus on language. But strength & mightiness of language is unquestionable hence we directly pray book and through which try to connect to god which is not describable as that is an unseen mechanism and mechanism has no face, size or shape. As in some faiths there is a ritual to pray and consider book as god but as human do picked wrong interpretation of why we pray book, main purpose of praying book is to praise the idea and do our karma as per the description given in the book and through which we may feel that god and purpose of our existence on this earth.
Let me give an example how idea is powerful than object itself, to carry on the idea or to convey idea to human need a tool and which is one and only language. Idea is an indestructible phenomena as it has no shape for example Taliban creator Osama-bin-laden given an idea of Jihad to extremists and now even after his death world is suffering from attackers who is carrying on idea given by osama. So language has played a major role for all this mess whose director & writer is osama and language only can solve this issue that means by talking & discussing issues but not with guns. Somebody said it right that eye for an eye solution to problems will make this whole world go blind.
