Page "Existence of God" Paragraph 20

Since God ( of the kind to which the arguments relate ) is neither an entity in the universe nor a mathematical object, it is not obvious what kinds of arguments / proofs are relevant to God's existence.

Even if the concept of scientific proof were not problematic, the fact that there is no conclusive scientific proof of the existence, or non-existence, of God mainly demonstrates that the existence of God is not a scientific question.

John Polkinghorne suggests that the nearest analogy to the existence of God in physics are the ideas of quantum mechanics which are seemingly paradoxical but make sense of a great deal of disparate data.
