This is the logical problem with miracles. It’s never reasonable to believe that a divine force has intervened because there will always be a more likely explanation. A miracle is an occurrence which is so unlikely that only the intervention of the divine can explain it. That means that any other explanation for the occurrence, no matter how ridiculous, must be more likely than divine intervention. And a reasonable person must prefer the likely explanation.
If a mountain range (harmlessly) sprung up in the middle of the Pacific and spelled out, in comic sans, “LDS is the true religion -XOX Jesus”, it’d still be more likely that this was a natural phenomena or alien intervention than the hand of God.
This creates a paradox where both of the following statements are true:
Belief in miracles is never reasonable.
Reason can’t confirm a miracle, and thus is an inadequate tool to evaluate them.
