Yet they claim to accept so many other scientific theories, such as gravity and chemical bond theory.
Actually, it seems to me that the best example of all is the germ theory of disease and related medical fields. It seems obvious from the stories in the Gospels that the Bible teaches that seizures are caused by demons, yet when a Christian's child has a seizure, that Christian (except in very rare denominations, whose children are prone to dying from lack of medical attention) doesn't call his pastor, he calls his doctor, who has learned how to treat seizures from science, not the Bible.
Or how about astronomy? Since Genesis one teaches (despite attempts by Christian translators to cover this up) that the sky is a hard dome holding up water, why do they accept astronomy's teaching that the stars are really big, burning balls of gas, many of them bigger than the sun and thousands of light years away?
