not to mention broken natural laws like floating axe, man living in a whale belly, talking dunkey, or sun moving during the battle to extend daylight.
Ah, these are better examples. But it was the foremost prophet of the time who caused the axehead to float, which implies that power from God was involved. We would have a bigger problem if it was some regular guy who did that to get his axehead back.
Living in the whale's belly is easier to believe; whales breathe air like we do, and he was only in there three days, which is the limit on how long someone can survive without fresh water.
I was taught as a Witness that the talking donkey had an angel giving him his voice like the serpent in Genesis 3, but (just like in Genesis!) it doesn't actually say that in the account. So yes, that's a bit weird. This account always stood out for me as a child.
The sun ceasing to move was not breaking a physical law from an ancient perspective, and that was the perspective I was speaking from. The Bible canon was decided on long before the Earth was theorized to revolve around the Sun.
I sitll say that, compared to all these examples, 450 (or 4500) foot tall men are harder to believe in and were probably a basis for rejecting the text. of course, there may have been theological parts that were troubling, too; I haven't read it so I don't know how well it would mesh with the Bible canon.
If the Book was written as late as 100-50BCE like HTBWC indicated, then it was possibly too late to be accepted by Jews as OT canon and thus was omitted by Christians as well.
