"There's probably no God. Now stop worrying and enjoy your life"
"There is no God. [To] do good is human. What we ourselves do is what matters"and my personal favorite
"God is with a probability bordering on certainty a Czech folk singer. Relax. He will do nothing to you,"are the posters in question. The link is to an Austrian site, and the text is in German, but the three options are (in order):
Ich finde sie sehr gut. ("I find it very good" -- or, "I like it")
Sie stört mich. ("It bothers me")
Sie ist mir egal. ("It does not matter to me")
in case you would like to go and vote.
But that's not why I'm posting this. I'm posting it because of the following comment, found at Pharyngula:
Here in Italy the UUAR (italian acronym for Atheists and Agnostic Rationalists union) tried to put the same message on a bus in Genoa, but the advertisement society refused.
In a more recent episode, the UUAR put up signs with the same message (The bad news is that god doesn't exists...) and the signs were taken down by police because it offended religious sentiment.
In a funny aftermath, the UUAR choose a substitute message:
"The bad news is that Zeus doesn't exists. The good news is you can say that about Zeus".
Funny and very sad at the same time.
