One may say: "prove that god exists". This may be followed by: "well, prove that god doesn't exist". The real question is, which of the above questions is more appropriate to ask? Is there even an answer? Is one more appropriate than the other? My opinion is, yes, one of the above questions is wrong to ask. All religion and all faith aside, there has yet to be found any definitive evidence for a god. Nothing that can be observed, even with our best scientific instruments, has even suggested the existence of a god. It is therefore a fact that a claim that god exists is an extraordinary claim. And extraordinary claims dictate the need for proof or evidence. If I said I had the ability to levitate objects with my mind, you might ask to me to prove it. This would of course be a legitimate request, simply because science has yet to find any evidence for telekinesis. Now, imagine that I responded by saying "hey, prove that I can't"! Most would agree that this response is ridiculous, and does nothing to support my extraordinary claim. With that in mind, it is my opinion that anyone who asks you for proof that god doesn’t exist, is not to be taken seriously at all. Again, a claim that a god exists is, at the moment, an extraordinary claim. As Carl Sagan once said, "extraordinary claims require extraordinary evidence". Only when there is a lack of evidence will people resort to ridiculous counter-questions such as "prove me wrong". The burden of proof should always lie with the person making the extraordinary claim. Any opinions on this are welcome.
