Where's your messiah now?

Just read an interesting in the New York Times about atheists in the UK starting their own bus advertising campaign. Their tag line was "There's probably no god, so stop worrying and enjoy your life." Apparently the "probably" was necessary for truth in advertisement laws(!) Don't know why the religious ads don't have to admit a gray area as well. The the American Humanist Association started running ads in Washington w/ a man in a Santa suit w/ the caption "Why believe in a god? Just be good for goodness' sake." The Australians couldn't get permission but I thought theirs best: "Atheism: Sleep in on Sunday mornings." Now that's effective advertising.
