I can't speak for him, and it does seem that he may take the very 'academic' view and believes that absence of evidence for existence can never be taken as evidence for non-existence. If that is the case, then, as I have indicated in my exchanges with him, I do not support that aspect of his belief - for reasons I have explained. As I have also said to him, if that is his position (and he wopuld prefer to call that a 'logical deduction', rather than evidence', then I would say that is essentially semantic. ....1) That is not what stillp believes, and for which you have expressed your support.
.... I think he is probably far too intelligent and sensible to not accept that if evidence for something's existence would be 'glaringly obvious' if that something existed, that the absence of such evidence then essentially amounts to 'proof' of non-existence, whether one calls it 'evidence', 'a logical deduction' or anything else.
As I said near the start of this tangential discussion, I didn't want to get involved in 'it' in an Electrics forum. However, as so often happens, I allowed myself to get drawn into ongoing, albeit fairly non-specific, discussions - but seeing where this page of the thread is now going, I think it's probably time for me to be true to my initial intent. If anyone wants to discuss religion with me 'off-list', they know where to find me!2) I refer you to the original subject of existence, and invite you to to apply that logic to it.
