Jeff said: You take Sagan's point out of context, first of all.
How so? "The absence of evidence is not evidence of absence" is a truism and speaks for itself. It has universal application. Logically, nothing is ever categorically proved false by absence of evidence. And as I said, Theists have evidence, just not conclusive proof.
Jess said: Secondly, while it is true, Sagan also allowed that something can indeed, be proven false.
Sagan didn't say that everything could be proven either way, or that it could always be proven now. Of course some things can be proven true or false. But not everything. The point is God is not one of those things, not yet. If you think you can without using the argument from ignorance, then go ahead.
Jeff said: From wikipedia (the same one you selectively quoted from)
I didn't selectively quote, I just didn't continue into a section that wasn't relevant. As I said, not everything can be proven either way, God is one of them, so why quote the obvious truth that some things can be proven false, which is not relevant to something which can't be?
Jeff said: So, for the sake of this discussion, it seems appropo to say that there is a high probability that god doesn't exist. There is a small probability that Jesus is looking at this conversation and laughing his ass off.
LOL. Seeing as we have so little knowledge to base this judgement on there is no way to reliably gauge probability. So, again, it's just opinion, belief, dressed up in ill-fitting disguises like "conclusions" and "probability". And, in any case, even if probability could be gauged, that would not be a truly atheistic position - which is "God does not exist" - but rather the "God probably doesn't exist", and probability does not establish fact.
