Refuting Evolution, Chapter 8
Teaching about Evolution addresses this assumption:
It assumes that the rocks being analyzed have not been altered over time by migration of atoms in or out of the rocks, which requires detailed information from both the geologic and chemical sciences.
This is a huge assumption. Potassium and uranium, both common parent elements, are easily dissolved in water, so could be leached out of rocks. Argon, produced by decay from potassium, is a gas, so moves quite readily.
There are many examples where the dating methods give ‘dates’ that are wrong for rocks of known historical age. One example is rock from a dacite lava dome at Mount St Helens volcano. Although we know the rock was formed in 1986, the rock was ‘dated’ by the potassium-argon (K-Ar) method as 0.35 ± 0.05 million years old.9 Another example is K-Ar ‘dating’ of five andesite lava flows from Mt Ngauruhoe in New Zealand. The ‘dates’ ranged from < 0.27 to 3.5 million years—but one lava flow occurred in 1949, three in 1954, and one in 1975!
What happened was that excess radiogenic argon (40Ar*) from the magma (molten rock) was retained in the rock when it solidified. The secular scientific literature also lists many examples of excess 40Ar* causing ‘dates’ of millions of years in rocks of known historical age. This excess appears to have come from the upper mantle, below the earth’s crust. This is consistent with a young world—the argon has had too little time to escape.
If excess 40Ar* can cause exaggerated dates for rocks of known age, then why should we trust the method for rocks of unknown age?
Another problem is the conflicting dates between different methods. If two methods disagree, then at least one of them must be wrong. For example, in Australia, some wood was buried by a basalt lava flow, as can be seen from the charring. The wood was ‘dated’ by radiocarbon (14C) analysis at about 45,000 years old, but the basalt was ‘dated’ by the K-Ar method at c. 45 million years old! Other fossil wood from Upper Permian rock layers has been found with 14C still present. Detectable 14C would have all disintegrated if the wood were really older than 50,000 years, let alone the 250 million years that evolutionists assign to these Upper Permian rock layers.
According to the Bible’s chronology, great age cannot be the true cause of the observed isotope ratios. Anomalies like the above are good supporting evidence, but we are not yet sure of the true cause in all cases. A group of creationist Ph.D. geologists and physicists from the Creation Research Society and the Institute for Creation Research are currently working on this topic. Their aim is to find out the precise geochemical and/or geophysical causes of the observed isotope ratios.13 One promising lead is questioning Assumption 1—the initial conditions are not what the evolutionists think, but are affected, for example, by the chemistry of the rock that melted to form the magma. [Update: It turned out there is strong evidence that decay rates were much faster in the past. See the results of their experiments in Radioisotopes & the Age of the Earth volumes 1 and 2.]
Evidence for a young world
A number of other processes inconsistent with billions of years are given in the booklet Evidence for a Young World, by Dr Russell Humphreys.
Creationists admit that they can’t prove the age of the earth using a particular scientific method. They realize that all science is tentative because we do not have all the data, especially when dealing with the past. This is true of both creationist and evolutionist scientific arguments—evolutionists have had to abandon many ‘proofs’ for evolution as well. For example, the atheistic evolutionist W.B. Provine admits: ‘Most of what I learned of the field in graduate (1964–68) school is either wrong or significantly changed.
Creationists ultimately date the earth using the chronology of the Bible. This is because they believe that this is an accurate eyewitness account of world history, which can be shown to be consistent with much data.
