Even if not, the next natural inclination would be to demonstrate power over souls/minds. This would most easily be done simply by causing me to believe in the afterlife directly and making me aware of this causation of belief while doing so. (This doesn’t, I feel, impede rationality because it does not prevent me from reassessing the situation based on my newfound set of priors.) Alternatively, causing me to experience mindspaces hitherto unavailable to me would also help in demonstrating a separation of traditional physiology and mentality. Witnessing all places on Earth simultaneously, or other such parlor tricks, would also do nicely there.
