If the Bible is not true, then it’s a fairy tale.
But if true it’s a history book.
Don’t miss the fact that there’s nothing intrinsically deniable in the Bible. By this I mean that in order to claim any part of the Bible is untrue, you must necessarily argue from a starting point of secularism.
You sound like a person who listens to logic. Here’s some: if God was able to create the universe, then logically he has the power to accomplish everything in the Bible.
This statement is certifiably untrue. The Bible describes events which supposedly happened in our world at specific times. They either happened, or they didn't. That's not a "secular point of view" unless by "secular" you mean "reality based." That is not a position you want to try to defend. And in fact, I'm not aware of any Apologist who ever has.
If the Hebrews claim to have wandered around in the desert for forty years but left no trace of their passing found by archaeologists, we have an obligation to regard their claim as untrue unless we can determine some reason why all trace of them would disappear from a particular period in history. That's not a matter of faith.
