Really? If I may ask, how did you manage to read about the Global Flood, a miraculous Exodus, an unparalleled military conquest, a man-swallowing big fish, a virgin birth, possessed and suicidal pigs, a cursed fig tree, a magical fish picnic, a stroll on the lake, the resurrection of the dead, and zombies strolling the streets of Jerusalem, and come out with no opinion?
Well, the way I did it was to be entirely open to the idea that miraculous things can happen. Although I have opinions now, I could have asked the same question with no opinion ten years ago, wondering if there was any evidence that those miraculous things did or didn't happen.
There can be very little likelihood of evidence for or against Jonah and his whale, but much likelihood of evidence for or against millions of people crossing the Red Sea, followed by the destruction of the entire Egyptian army. At the start of looking for that evidence, it is quite easy to have read the whole Bible and have no opinion about whether there is evidence for or against those miraculous things happening.
