We all know it couldn't be some unknown like Richard Dawkins, Bertrand Russell, Carl Sagan, etc.
As much as I've read, Sagan openly concidered himself agnostic. But I've never heard of the author so HE couldn't be the world's most notorious atheist, unless of course he's secretly killed hundredes of people, eaten them and hidden their bones in other people's basements. Then I'd say he's definately the worlds most notorious atheist, but at least Jesus forgave him lol
