PROBABLY?

It is quite likely that you have heard of the Atheist Bus Campaign that receives

donations to place advertisement on the side of buses that read:

THERE'S PROBABLY NO GOD. NOW STOP WORRYING AND ENJOY YOUR LIFE.

Lets for a moment presume that the first statement is true. Lets assume that "there's probably no god". Would it follow that we should forget about God and do what ever we want? What I want to know is why atheists put the word 'probably' in the first statement at all, because 'probably' implies that there is a chance, however small, that there is a God. I was considering the issue a few days ago and realized that it just isn't logical. Even if the probability of there being a god was one in a billion would you risk spending eternity in hell just so you can ignore the God who loves you in this life. Are you prepared to risk so much on a bet? If you loose the bet you will be condemned to the worst suffering imaginable and if you win and there is no God... what will you have gained?
