The bible contains many instances of supernatural, seemingly-implausible events. And those passages inevitably lead to debates about whether the bible offers literal truths about those events. Those debates are frustrating, in part because spiritual debates almost never break one way or another based on scientific evidence. But those debates also can be frustrating due to way in which they seem to inflame passions on both sides.
So at the very risk of inflaming those very passions, let me state how I see things.
First, I think it's wrong to ask whether the entire bible is divinely inspired. Rather, we should ask whether, despite being crafted by humans, the bible contains a single word, a single turn of phrase, a single punctuation mark, or a single capitalized letter that might have received divine guidance to appear that way. (If your answer is "No," then you're probably at the wrong blog!)
If we accept any morsel of the bible as divinely inspired, then we must conclude that God intends the bible as a communication device. Consequently, even the parts that appear supernatural or implausible must contain important truths. But perhaps those truths are spiritual rather than scientific. After all, if one wishes to learn calculus, one should read a calculus book. But the bible exists to teach us spirituality.
Take the fascinating story of Jonah and the fish. Is that story trying to convey information about some heretofore unknown sea creature, as well as insights about a human's ability to survive inside that creature? I don't know. Maybe. It's a fascinating argument, but not one that we'll resolve (or win).
More importantly, I think, is that the story of Jonah is trying to convey that God's will cannot be thwarted. Jonah tried to ignore God, as we all do sometimes, but it didn't work. (The three-day banishment inside the fish also foreshadows Jesus' death, as Jesus himself noted.)
Or take the part of the bible that really gets people worked up: the Genesis account of creation. Is God trying to give us a point-by-point scientific description of how existence came to be? Again, I don't know. Maybe.
Or is God trying to convey spiritual truths of how existence came to be, that God controlled everything from the beginning, while giving humans and their attachment to that existence central importance.
I think, when reading the bible, it is more useful to focus on spiritual truths than scientific truths.
