Omar, just noticed that you gave the God Delusion 10/10. I can't remember much of it but I remember disagreeing with just about everything he had to say. I felt like I was reading a book written by an atheist scientist picking and choosing any argument he could find in philosophy against the existence of God.
I can only remember the main problem I had with it, which was that he thought the "prayer experiment" was a really good argument against the existence of God. It was a very superficial experiment in my eyes.
I read a lot of it when I was starting to think more about whether Islam was the truth, right at the beginning of my "lack of evidence for Islam crisis" but I was still very religious. Perhaps I was biased at the time when I was reading it... Probably a good idea for me to read it again actually, it'll remind me what I was thinking about at the start of my crisis
I had read Dawkins book when I first apostated. Since then I have read many better books than that one. For me, that book was a turning point because most of what was in it was a confirmation of what I was already thinking to begin with. A better book than that for the layman is "Atheist Universe" by David Mills.
I have read Dawkins book again and heard the audiobook twice. I would say that the book mainly attacks religion and not the concept of God itself. For arguments concerning God etc, you would be better off reading books by philosophers such as Quentin Smith, Michael Martin and Ricki Monnier.
