DMD Publishing Co. is the home of Glenn R. Morton, a Christian petroleum geologist who nearly lost his faith completely after years of involvement with young-earth creationism, flood geology and other religiously-inspired pseudoscence.
In order to get closer to the data and know it better, with the hope of finding a solution, I changed subdivisions of my work in 1980. I left seismic processing and went into seismic interpretation where I would have to deal with more geologic data. My horror at what I was seeing only increased. There was a major problem; the data I was seeing at work, was not agreeing with what I had been taught as a Christian. Doubts about what I was writing and teaching began to grow. Unfortunately, my fellow young earth creationists were not willing to listen to the problems. No one could give me a model which allowed me to unite into one cloth what I believed on Sunday and what I was forced to believe by the data Monday through Friday. I was living the life of a double-minded man--believing two things.
By 1986, the growing doubts about the ability of the widely accepted creationist viewpoints to explain the geologic data led to a nearly 10 year withdrawal from publication. My last young-earth paper was entitled Geologic Challenges to a Young-earth, which I presented as the first paper in the First International Conference on Creationism. It was not well received. Young-earth creationists don't like being told they are wrong. The reaction to the pictures, seismic data, the logic disgusted me. They were more interested in what I sounded like than in the data!
Rather than dealing with the problems thrown up by the data, Creationists resorted to name calling;
'like your father, Satan' (Carl R. Froede--I am proud to have this one because Jesus was once said to have been of satan also.). There's lots of interesting stuff to read here, though some of his attempts to reconcile the data with Genesis smacks of special pleading. (via Ken MacLeod).
