I think that as you say
pulse1 The difference between evidence and proof is an area which many people have differing views In my case the term " there is evidence that X caused the crash" means that there is also proof of that fact, the term "there is evidence that X may have caused the crash" means that it's a probability approaching 1 but is not proven. It all comes down to the use and interpretation of the English language.
I for one am guilty of sloppy english quite frequently, I know what I mean but other people put a different interpretation upon it.
