Richard Dawkins - "What if you're wrong?"

"What if you're wrong?" implies that we should just throw evidence-based probability out the window any time we are faced with deciding whether to believe any tenet that is not conclusively proven. The magnitude of evidence against creation, deities, and the supernatural does not eliminate the fact that it is impossible to prove the non-existence of something.  Essentially, it will always be impossible to claim with 100% certainty that god does not exist. But because we cannot conclusively prove that god does not exist we should avoid making the claim in fear of being wrong regardless of  the growing mountain of evidence against such an existence? The fact is this, both theists and atheists might be wrong. However after I review the arguments in favor of both and the total sum of evidence collected by each camp, I have chosen the only option that has any evidence. I'm quite comfortable with my choice and not too worried about being "wrong".
