I fear this is too far out of anyone’s experience to usefully trigger or examine any intuitions. And it’s so physically impossible (how could the past change, full stop, but even more without changing the present and the future) that there’s not much to learn about introspecting on it. the bayesian knowledge questions (what evidence could POSSIBLY make you update those beliefs that way) aren’t even needed to make this question meaningless.
