@The OP Q.
You can try, but it's going to be difficult, as proof has a distinct and stringent set of requirements that exceed those for, for example, evidence. A modus tollens is a proof by means of absence, but you need the full spread of conditions to establish that it's a valid application , or a sound application...to -prove- it. Once you open that can of worms some really strange things happen in the conflux between propositional logic and natural language.
P implies q, not q, therefore not p. Seems simple...right, now try to plug english words in and watch how hilariously -anyone- with an interest can object.
