"i am agnostic, certainly not atheistic, since i think atheism is not provable" - xelder
Atheism is a position taken in relation to Theism in that it rejects the claims of Theism; therefore there is nothing that needs to be proven. The onus is on the positive claim, i.e. there is a god, to be proven truthful. It would be silly to expect someone to prove beyond all reasonable doubt each and every outlandish claim made, whether that be claims about a god or indeed anything else. The onus of evidence is always on the person making the positive claim. Yes, an "Atheist" may state there is no God but that, of course is a positive claim requiring some evidence.
A JW holds an Atheistic position in regards of the claims of all the other gods of this world. In fact it has been said that the only difference between a Christian and an Atheist is that the Atheist has gone just 1 god further...
