Whether God's Existence Can Be Proven II

One could, of course, respond to the assertion "God's existence cannot be proven" that sufficient evidence must be provided to justify the belief that it is impossible to prove that God exists. This is a legitimate strategy; but, it seems to carry an unwarranted assumption. Namely, the assumption that the one making the assertion has a clear understanding of what he is asserting when he claims, "It's impossible to prove that God exists." The response most likely to further the discussion - and a rather disarming one - is to offer the counter-claim that the one making the assertion actually does not understand what his position is, and is not exactly clear about what he is asserting.

Before going further, however, we should note that the shift in language from "God's existence cannot be proven," to "It's impossible to prove that God exists," is not unwarranted: the modal terms "cannot" and "impossible" are prima facie interchangeable, such that substituting one for the other does not change the truth-value of the propositions.
