Whenever we ask for those "sophisticated" arguments for the existence of god(s) we are directed to various Courtier's Replies discussing how to rationalize the properties of various gods. They all begin with the assumption that god(s) exist. As I pointed out earlier, there's no reason why an atheist should care about things like the problem of evil. It makes about as much sense as debating the cut of the Emperor's new clothes or the stylishness of his new hat.
Alvin Plantinga is one of these "sophisticated" theologians. Listen to him explain why atheists should believe in god(s). Is this really the best they can do?
1. The second most common complaint is that we don't even have good arguments for atheism—at least not as good as those thinkers of the 20th century who were full of angst over not having a god to believe in. Apparently modern atheists aren't very sophisticated unless they are contemplating suicide.
[Hat Tip: Jerry Coyne: Plantinga on why he believes in God, dislikes the New Atheists, and finds naturalism and evolution incompatible.]
