THE GEOLOGIC COLUMN

A schematic representation of the 'geological column', allegedly representing geological strata going back hundreds of millions of years, and showing an increase in complexity of living things during this time.

By collating rocks from various parts of the world, an imaginary geologic column has been built up, with the oldest rocks at the bottom and the youngest at the top.

Evolutionists claim that when this column is examined from bottom to top, the fossils in it show a gradual development from simpler to more complex forms of life.

This all sounds very convincing – but how do they know the age of the various rocks, so as to be able to place them in an order of increasing age?

The simple answer is that in general, they have been dated by the fossils they contain. If the fossils are ‘primitive’, then the rock is old and if more complex, the rock is younger and so on. Therefore based on the fossils they contain, the rocks are dated and put into an ascending order of age.

Then evolutionists say – ‘Look, the simplest fossils are at the bottom and the more complex ones at the top – that's proof of evolution.’ In other words, they date the rocks on the assumption that evolution is a fact and having done that say that the rock sequence proves evolution to be correct.

CIRCULAR REASONING

This is not misrepresenting the situation. One writer says: ‘If a geologist wished to date a rock stratum he asked an evolutionist's opinion on the fossils it contained. If an evolutionist were having difficulty dating a fossil species, he would turn to the geologist for help. Fossils were used to date rocks: rocks were used to date fossils.’ 25

This example of circular reasoning is probably not detected by the general public but it has long contained a valid objection, with implications for Darwinian evolution. For example, one critic says: ‘Here is obviously a powerful system of circular reasoning. Fossils are used as the only key for placing rocks in chronological order. The criterion for assigning fossils to specific places in that chronology is the assumed evolutionary progression of life; the assumed evolutionary progression is based on the fossil record so constructed. The main evidence for evolution is the assumption of evolution! Consequently there is certainly no real proof that the vast evolutionary time scale is valid at all...Here is one of the most classic and subtle examples of circular reasoning in all the complex history of metaphysical opposition to Biblical creationism.’ 26

An American physician also writes: ‘Any honest geologist will admit that … the age of geologic strata or the dating of fossils, are frequently the result of ‘circular thinking’ and, as such, have an inherent potential for significant error.’ 27
