This was the scientific age, and people wanted to believe that their traditions were in line with the new era, but this was impossible if you thought that these myths should be understood literally. Hence the furor occasioned by The Origin of Species, published by Charles Darwin. The book was not intended as an attack on religion, but was a sober exploration of a scientific hypothesis. But because by this time people were reading the cosmogonies of Genesis as though they were factual, many Christians felt--and still feel--that the whole edifice of faith was in jeopardy. Creation stories had never been regarded as historically accurate; their purpose was therapeutic. But once you start reading Genesis as scientifically valid, you have bad science and bad religion.
