Could Genesis have been written any other way?
What would the Israelites have said a bloke wondering in from the desert pontificating the following:
"Yes, God has made it plain to me. The earth is a tiny dot in the middle of an unimaginably vast universe, which originally boiled down to a singularity of infinite density. Matter then was so hot even the atoms decomposed, and matter anti-matter annihilation flashed energy across the cosmos. Thousands of millions of years later, the earth was created, and then man came along. after the dinosaurs and other prehistoric animals had died out, etc...."
Well, perhaps some of them would have looked up from their animal hide tents, looking slightly bemused. The rest would probably have thrown rocks at him and called him a nutter.
Genesis can't provide successfully for both the modern world and back then. It's simply couldn't keep both satisfied.
But does this matter?
In my opinion Genesis still answers all the important and relevent questions we might have about the origin of the universe and humanity.
Did God start it? Yes
Is there a purpose to it? Yes
Did God give humans a soul? Yes
Did humans turn from him to sin? Yes
etc..
Just because I'm not convinced It's not 100% true has little to no effect on my belief. God wanted it written as it is. All scripture is God Breathed, and is USEFUL [excuse my paraphrasing]
If Genesis had been written in such a way as to agree with scientific theory more readily, would my religion and belief be different?
Not a bit.
