Don’t try to reason with a man who is trying to use the scientific method (hypothesis and experiment) to disprove science. “You cannot reason a man out of a position he was not reasoned into.”
Actually that's pretty cool. Any serious attempt to utilize the scientific method will inevitable lead to something that resembles current scientific knowledge.
I guess the fun here is if he's intellectually honest about his observations meeting his theory, or whether the cognitive dissonance will keep his beliefs on the rails he expects. Ideally he'll find himself being drawn back towards the evidence based solution.
Also, I believe it's hard for smoking craters to rationalize about their observations.
