在我二十出头的时候，我曾思考过上帝是否存在。George H. Smith 写的《Atheism: The Case Against God》和 Richard Robinson 写的《An Atheist's Values》这两本书让我确信了上帝并不存在。
In my early 20s I contemplated the existence of God. The books "Atheism: The Case Against God", by George H. Smith, and "An Atheist's Values", by Richard Robinson, persuaded me that God does not exist.

为了回应这个区别并不跑题，我想推荐的一本书是 George H Smith 写的《Atheism: The Case against god》。
To respond to this distinction and stay on topic, a book I'd recommend is Atheism: The Case against god by George H Smith.
