It seems to me that the human mind is constructed in such a way that we can never accept a negative proposition with the same degree of certainty we accord a positive affirmation.
God either IS....... or He is NOT.
Once a man has become CONVINCED that He IS, in a Supernatural method of conviction, the question is forever settled in his mind.
It is impossible for the Atheist to hold his unbelief with the same conviction.
I think that explains in part why they continually attempt to engage in debates with believers.
