The point is, why read the often outlandish tales and fables of the Bible, largely written by unknown authors, when we have attributed works of Greek philosophers and mathematicians. It was the Greek polymath Eratosthenes who described a spherical earth as opposed to the Biblical flat earth.The point is, why read Agatha Christie mysteries when Sir Arthur Conan Doyle mysteries have the same elements?
The answer is the different perspectives and the different approaches. Yes, the Bible, Aesop's Fables, etc. have some of the same elements, but the perspectives and approaches expand our own minds, perspectives, and thoughts.
Ask yourself: Why the need to select one and be dismissive of it?
For centuries, it was the position of the Catholic Church that dissent from their orthodoxy was blasphemy and that could result in your head being removed from your torso.
Yes, there are different perspectives and fortunately, the inertia of history caused the perspective of the Church, one requiring complete subordination, to wane as western civilization pushed forward with exploration of the physical sciences.
