Renown Atheist Richard Dawkins Isn't Entirely Sure God Doesn't Exist

LONDON — A controversial Oxford University professor billed by many as the world's "most famous atheist" now says he is not 100 percent sure that God doesn't exist — but just barely.

In a 100-minute debate with Archbishop of Canterbury Rowan Williams last week, Richard Dawkins surprised his online and theater audiences by conceding a personal chink of doubt about his conviction that there is no such thing as a creator.

But, to the amusement of the archbishop and others, the evolutionary biologist swiftly added that he was "6.9 out of seven" certain of his long-standing atheist beliefs.
