> claiming "there's no evidence that happened" is nonsense - you just heard the evidence, and any reasonable person would conclude you did.

I am not sure about that. If someone claims that you had stole something from a store, which you know you didn't, responding with something like "where is your evidence/you have no evidence" sounds perfectly reasonable to me.

if they say they saw you stealing - yes, that's evidence. If they just say "you stole" then yes, the correct question would be "why do you think so, on what evidence" - but a first-hand experience is definitely evidence. Moreover, often it'd be the only evidence available (not all stores have 100% video coverage). Of course, as always, the purported witness could also be lying, but if they claim they personally saw you stealing, this definitely counts at least as evidence, if not proof.
