 One way to defend the second premise is to review the relevant evidence and argue that it is ambiguous (Le Poidevin 2010: chapter 4; and Draper 2002). Another way is to point out that atheism, which is just the proposition that theism is false, is compatible with a variety of very different hypotheses, and these hypotheses vary widely in how well they account for the total evidence. Thus, to assess how well atheism accounts for the total evidence, one would have to calculate a weighted average of how well these different atheistic hypotheses account for the total evidence, where the weights would be the different intrinsic probabilities of each of these atheistic hypotheses. This task seems prohibitively difficult (Draper 2016) and in any case has not been attempted, which supports the claim that there is no firm basis upon which to judge whether the total evidence supports theism or atheism.
