It's likely the Bible was a text lifted by the Hebrews from the Hyksos, themselves having stolen it from an ancient Indo-Aryan tradition produced by a civilization we are not even aware of today. It is altogether possible that the Bible is hundreds of thousands of years old, perhaps millions of years or even older.
Nevertheless, the stories in it continue to be the sacred truth, a higher truth than Richard Dawkins has ever dreamed of in his wildest imagination. There is not a word of scripture that is not imbued with a thousand times the value of any book ever produced by a mere man in terms of it's spiritual value in the conveyance of wisdom.
In the story of Sodom and Gomorrah, we learn of the fate of all declining civilizations that are destroyed by God's wrath.
In the story of the Tower of Babel, we learn of the failures of globalism and multiculturalism as they have occurred again and again, possibly going back into the mists of antiquity.
In the story of Esau and his brother Jacob, we learn that better races of men have lost the blessing of their father not because they were unworthy but due to treachery and circumstance.
In the story of Eden, we learn that the man who blushes, the original child of God, was corrupted by having his stock polluted by the seed of serpents, the genetics of snakes.
In the story of Abel and Cain we see that the original founders of all civilization are always descended from murderers and liars.
We see that all the mistakes made by mankind are remedied by the sacrifice of the living word of God, Jesus, who died in our place in order that we could be forgiven our sins and rejoined to our father in heaven.
The funny thing about the Bible is that it is always the most relevant book you can read, no matter what era you are born in. Whatever you learn from scripture you will find will apply to your life right now more than anything some mere man can ever say or write. When you learn a lesson from the Bible, you have acquired real understanding.
