You can't prove it was formulated from truth and fact.....its a faith based religion.....sorry
However this is a unique book, written in such a way that it cannot be understood until a special part of the brain is opened up, the part that can understand the spiritual part of our world. If you are only able to see the world without God in it, you will have not idea what this book is speaking about.
For instance in the very first chapter it explains the steps God to in creation. The translators said in the first day God created light as translators used for the Hebrew Owr, meaning all goodness. It wasn't until the fourth day that he created the light we know about. That would make no sense at all to a secular mind.
What you are asking for is that your secular mind be opened to the reality of the spiritual world you live in. if you are blind to it, that is just the way it is. You would have to ask to understand, and it is in the words of the bible you are questioning that understanding of bible comes.
