I would file myself somewhere around 6 -
6.00: Very low probability, but short of zero. De facto atheist. 'I cannot know for certain but I think God is very improbable, and I live my life on the assumption that he is not there.'
Now you are looking for "proof" of why I hold this position. I hold this position because I find no reason to hold the opposing position. I find there to be a total lack of evidence for God's existence.
Now of course, this falls into the category of "absence of evidence is not evidence of absence".
In the fossil evidence debate, creationists raise the point of the lack of transitionals fossil evidence. To which one reply could be that "absence of evidence is not evidence of absence". But in that case it is not a total lack of evidence situation. Rather is is a gap in a chain of evidence. Such gaps are to be expected, and it is also expected that at least some of the gaps will later be filled. Thus I find the "absence of evidence is not evidence of absence" to be legitimate.
For God on the other hand, there is not the situation of being gaps in a chain of evidence. There is a total lack of what I would find to be compelling evidence. Thus I find the "absence of evidence is not evidence of absence" to be illegitimate. The phrase mutates into "TOTAL absence of evidence IS evidence of absence".
