The Bible and the many similar handbooks on life that existed over the years were the science of their day.

The difference now is the acceptance that a hypothesis is best challenged than accepted blindly. As nobody who had anything to do with the Bible etc had visited The Galipagos Islands, finch evolution didn't enter into it. However, eating of foods that go off in hot countries such as pork and shellfish, or circumcision were good sound public health measures.

Nowadays we have more sophisticated public health measures including monitoring flu in China in the summer of this year to concoct the flu jab given 18 months from now here in The UK. The Bible couldn't comprehend such logistics.

In fact, compared with the wonders of reality, the Bible must be so limiting, so parochial.
