GRISDA has
a paper by Warren Johns explaining why he thinks that scriptural geology failed in the 1800s. It has some good ideas. Here are his suggestions:
- Restricting flood layers to higher and higher portions of the geologic record
- Lack of human fossils in geologic strata
- The shift away from the hard facts of geology by the scriptural geologists
- The major journals and educational institutions were hostile to traditional religious beliefs
- The professionalization of geology made it difficult for part-time geologists (such as the scriptural geologists) to have a voice
- Liberal theology was replacing orthodox theology as the dominant view
