Whenever I see the phrase "irrefutable proof," it is a tip-off to me that the person who demands it is demanding in bad faith, because they can always retreat into the position that the proof is not irrefutable. We have multiple witnesses and participants, sworn testimony, photographic evidence, communication records, visible artifacts remaining, and surface samples...and this is not "irrefutable proof"? Well, then, what do you want beyond that?
