Question

I was asked a question: while it’s true, as you say, that Judaism’s uniqueness on various different parameters strengthens its credibility (the survival of the Jewish people, the uniqueness of the Jewish people, etc.), the very fact that many religions have tried to present a convincing religion weakens the force of Judaism’s arguments. Because it’s likely that out of many religions trying to present themselves as convincing, one or a few will appear convincing and unique. In other words, the question is: does Judaism’s uniqueness stand on its own, so that its improbability strengthens Judaism’s credibility? Or should we judge all religions as a whole, from which it is more likely that there would be a religion that presents arguments that seem unique?
For example, take fortune-tellers. We wouldn’t be impressed by some fortune-teller even if he said many correct things, since it is likely that out of so many people trying to predict the future, some of them will hit the mark exactly.
I thought to reject this argument by saying that Judaism has a certain a priori advantage over all other religions that sets it apart on its own: it is the best-known and most influential religion in the world, and therefore that places it in a category of its own.
What do you think?
