but to be sure that it couldn't be?
that there could NOT be a God?
Atheism is not the belief that there
could not be gods. Atheism is lack of belief in gods. Your brand of atheism has the atheist walking around actively denying something. Where some may have an "extreme aversion to anything resembling spirituality", it doesn't stem out of atheism, though that may lead to it once the "extreme aversion to anything resembling spirituality" resolves into "What should I have for lunch?"
The world breaks everyone, and afterward many are strong at the broken places. But those it cannot break, it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these, you can be sure that it will kill you too, but there will be no special hurry.
