Originally posted by Thequ1ckYou're still confusing evidence and proof. It's impossible to acquire the absolute proof you seem to be demanding, because the only thing you can prove in an absolute sense is a tautology (e.g. "X is either a knife or X is not a knife" - true for any X), and even that requires some sort of axiomatic logical system.
Yes and those classes of phenomena can either be observations or evidence.
But obviously you cannot have evidence without first making observations
(although some do try).
