You make a very strong mathematical case for the (very small) possibility/probability of there being a "god" (whatever that means).
But, perhaps, you could help me to understand why you see the need to find such a god?
Is it so that you will know how the universe was created? If it turns out that it was created by a "god", would that set your mind at rest? Or would you then want to know who created that god? If, as theists believe, that god was not created but just "is", then how much more exploration and explanation would you then be tempted to undertake to prove that assertion? And how is that different from the universe not being created but just "is"? I personally can't see why, if the universe itself is not accepted as first cause, that there would not be an infinite regression of first causes through a hierarchy of prior-cause gods?!
Or is it so that you would feel less responsible for your actions? Or is it so that you would somehow (god knows how?) categorically know what was right or wrong? Or is it so that you could question someone on what you should do tomorrow?
I just can't see why anyone would need a god! And given the infinitesimally small odds on there actually being one, why anyone would spend more than a minute of their lifetime searching for, or debating the possible form or existence of, such a hypothetical "god"!
Can you help me to understand the agnostic's need(s)?
