Can we be presented with the absence of God as a brute fact, one with no need of explanation or analysis etc.? How does this compare with what theism alleges to report?
This wasn't meant to be an implicit presentation of reasons for atheism. But it certainly seems we can - and should - question God in a way we perhaps even cannot do to His - supposed - absence from the world.
So atheism not because people make false claims for Him, anything of that sort, but I suppose just because it is indeed more parsimonious: atheism - how it describes the world - needs no explanation, or the inverse of the first cause argument (I didn't think of that denouement very hard).
