A vision a la that of Paul on the way to Damascus, especially if witnessed by several other people, would be quite convincing. Similarly, if there were a miracle witnessed by many people, none of whom had any agenda, and some of whom were skeptics who'd been convinced, or if it were caught on film, with no evidence of tampering or foul play, then I might be persuaded. Some startling piece of scientific or historical foresight in prophecy, with no ambiguity as to its meaning whatsoever, and with no chance of its arising by chance, would persuade me. So too would solid historical evidence, enough to persuade serious and impartial historians, that miracles were performed by figures like Jesus or Mohammad. If a prayer were answered in a way that defied the laws of science, and there was medical evidence that this had occurred, I would be persuaded. As for a deist god, I'm not sure what it would take to persuade me, nor how it could ever be proven, but a universe that appeared less like the work of an incompetent trainee deity on work experience, or a sadistic cackling cosmic fiend, would be a start.
