In my opinion, atheism requires a great deal of faith. If you rule out the existence of any god (i.e., a rational agent that brings life into existence), then you must also believe that a non-rational agent created human life. But given that humans are creatures capable of rational thought, this means that atheism entails the belief that a non-rational cause produced a rational result. I have never seen any evidence that this has ever occurred.
And not only does it require faith to believe that the cause of human life is a composite of non-rational, entirely random forces (in the absence of evidence that non-rational agents can produce rational beings), but it also calls into question the credibility of human Reason. Given that reason is what atheists tend to pride themselves on, it would seem that this would cause them problems.
I have never heard a convincing counter to this objection. Maybe someone else has?
Here is a link to a succinct essay that addresses this and other issues that atheism leaves unresolved:
Also, has anyone seen a convincing rebuttal of C.S. Lewis's revised argument against naturalism in Miracles? I am aware that he revised it due to some objections when it was presented as an independent article; but to my knowledge he addressed those objections in the revisions. And I have not seen any objections to his revised argument.
