Probabilities are usually defined in terms of events. P(B|A) = P(B,A) / P(A). If A = “the moon is made of cheese” then the measure P(A) = 0, and also P(B,A) = 0. So the conditional probability would be undefined.
You could adopt the position that probabilities should never be exactly 0 or 1. The moon might be made out of cheese after all, just with probability 1e-(1e1000). And quantum uncertainty pretty much guarantees that it is possible. Then what you are saying makes a lot of sense.
I’m not sure they should never be zero or one, but there is definitely a non-zero (and much higher than 1e-(1e1000) chance that the moon is made of cheese.
