That is exactly what he tackles in a very thoughtful way. He examines the definitions and the claims associated with them. He ties together so many and various disciplines in their search for truth and a basis for knowing.

@WilliamCharles Who is "He"?

@barjoe The host of the series. Forget his particular credentials but it doesn't matter as he delves into any of these issues with a rationalist's approach and willingness to be persuaded. He takes any of the claims with skeptic eyes, but for any of the topics, even more science themed ones, he seems to give all sides an opportunity to make their case and explain their viewpoint. That seems always a good model.

@WilliamCharles The only thing ambiguous about the existence of God is that you can't prove a negative. Belief in religious ambiguity exist only because "he" wants it to be ambiguous. Atheists know religious believe.
