An author has used Bayes’ Formula to determine the probability of God, given there is evidence of God : P(god│evidence of god). To determine this probability, you will need to subjectively estimate the following probabilities:
P (god) = _____
P(no god) = 1 – P(god) = ______
P (evidence of god │god) = ________
P (evidence of god │no god) = _________
Only God knows the right answer -- since these are all subjective probabilities.
Note: P (god) should neither be 1 (certainty of god) nor “0” (certainty of atheism) since neither of these two extremes have been proven (by theologians and/or scientists). A true agnostic would handle it this way: P (god) = P (no god) = .5 But suit yourself; these are your subjective probabilities.
