Since we're playing semantics here, I suppose I'll punt my two cents in. My take is that whether you state "I am an atheist based on..." #2 or #3 depends more on at what personal confidence level you move from "pretty damn sure" to "virtual certainty". I mean, at what point is it absurd to state, "I can't be
sure the sun will rise tomorrow but I think it probably will" rather than "The sun will rise tomorrow." Unless proven otherwise, of course. It may not be philosophically "pure" to state there is no god/God. But IMO I can have pretty damn high confidence in so stating. After all, believers have had literally thousands of years to provide evidence of the existence of a supernatural creator/entity. So far, no luck. I'm quite willing to be proven wrong. But in the interim, I'll go along stating that the sun WILL rise tomorrow.
