Hmm, wouldn't it just be not powerful enough? Well, that's not
my field :)

Ok then, you are right that people have no proof. But I think those people
mean something like "evidence no reasonable person can reject" rather than
proof in a scientific meaning. And the former is in my opinion what one
should look for in a case like this. As in too many discussions the combatants
are using words in different ways. I think you should interpret "proof" as
"evidence" and let the matter rest, or point out their sloopy use of the words.
Ah, sorry for telling you what to do... :)
