Mark Sharlow has written a solid paper critiquing Dawkins’ argument from complexity against the existence of God — the core argument in Dawkins’ book The God Delusion. The paper is called “Playing Fast and Loose with Complexity: A Critique of Dawkins’ Atheistic Argument from Improbability”. It’s not mind-blowing philosophy, but I think it does a nice job explaining some of what’s wrong with Dawkins’ argument. 

(And just to make clear, one can reject Dawkins’ argument for atheism while still being an atheist.)
