Hey guys I just finished an excellent book about this debate. It's called "Atheism Explained" by David Ramsay Steele. It Basically gives almost every argument for and against the concept of God. I have read most the of the "new" atheist books from Dawkins, Harris, and Hitchens and I didn't really care for them. This book however is level headed all the way through and I feel it is probably the most concise and well done book on the subject. Check it if you are an atheist or theist. The arguments are well laid out for both sides, but obviously the author sides with the atheist arguments.

Also a great quote I just found:
"I do not fear death, in view of the fact that I had been dead for
billions and billions of years before I was born, and had not suffered
the slightest inconvenience from it."
Mark Twain
