Evidence from an unusual victory

In the SD
Hello Rabbi,
I wanted to ask what you think about evidence for a particular religion following a victory or unusual influence on humanity.
For example, Muslims at the time of Muhammad had huge and unlikely victories against states and powers, which they considered to be strong evidence of their true religion. Both the speed of the spread of the faith and the strength of the victories in battles. What do you think about that? (The advantage is that these events were "marked" by the prophet and their a priori probability that some Falahim would defeat lesser powers).
Christians also have a similar claim, but for Muslims it is much more significant.
