Mike,
Babbling, huh. Like Colombo? Good choice for this forum. He has a delightful epistemological strategy.
Are you aware that Jehovah, if He is out there and wrote the Bible, says that He made a provision for us to "prove" Him scientifically. It's described in Malachi 3:8-12. The Materialistic Naturalists would like us to believe that He cannot be proven, but if He is the Creator, and says He created things so He could be "proven," then He is right about that, and not them. The only way to know, of course, is to do the experiment He describes, and see what, if anything, happens. This, to my knowledge, has only been done anecdotally, but always with reported "proving" of Him.
Remember doubting Thomas. It would be unkind to discourage such a person from finding their God, by telling them that they cannot put God to the test.
