Arguments against religion and God are the most useless. We atheists feel we understand why religion exists and what it means, but we are generally only looking at it on the most surface level. We naively debate religion as though we fully understand it, yet most of us have no experience with it. Reading a book on a subject does not make you an expert. You could just as easily read a book on skydiving and assume you are master of that as well.
Knowledge from a book is no alternative to experience. If you are able acquire the knowledge yourself, without reading it, then the book is not a viable tool.
