You started out with a claim about believing stories about Jesus. Said stories were backed up by witnesses who had little to gain by lying, and much to lose (and lose many of them did.) We should be entirely willing to entertain a so-called crazy person’s story, provided they can offer compelling evidence - just as the earliest Christians did.
Sure, you can argue that we should be skeptical whenever an extraordinary claim is made - then again, we live in a time where the reasonable explanation for, say… the beginning of the universe (and I don’t doubt this explanation, for what it’s worth) is that everything was compressed into a point smaller than a thimble, then there was an explosion, and billions of years later - the platypus.
Entirely reasonable explanations (When you start excluding the extraordinary as unreasonable) for the big questions of our existence are not available. They never were.
