Potassium argon dating is only done with
It's just one of the tricks that have been used to make the work a little more precise. I believe he has confused the use of index fossils with evolution.One creationist editor, who is more mellow than his unfortunate statement suggests, phrased the argument thus: Unfortunately the geologists date the rocks as the paleontologists tell them to. That passage might have come out of one of Henry Morris' books, except that Morris usually avoids crude slander. Hovind is not aware of the fact that by 1815 the broad outlines of the geologic column from Paleozoic times onward had been worked out by people who were mostly geologists.Once the worth of index fossils had been established on the basis of stratification studies, they could logically be used to extend the correlation of rock formations to other continents.At this point in time they were simply a useful tool for correlating rock formations.Evolution, working in tandem with geologic ages, can explain why we have index fossils, but evolution is needed to make the index fossils useful for dating strata.
This poses a fatal problem whether one believes in the accuracy of radiometric dating or not!
Studies done on the European continent soon demonstrated the universal validity of index fossils.
