Dr Laurence O. from the United Kingdom writes in response to our article Age of the earth, and CMI’s Dr Don Batten responds.

I am a PhD physicist and also a committed Christian. Having read your article I am shocked at the effort that has gone into defending what I consider to be a quite unreasonable position. Perhaps you have seen the Wikepedia website that discusses the age of the earth? There you will see that the earth has been aged by a large number of techniques, and the accuracy of the result (4.54 billion years) has been established to an uncertainty of 1%. The earliest estimates of the age of the earth were made before radioisotopes were discovered or the theory of evolution was thought of. These estimates (based on techniques such as the rate of cooling of an initially molten earth and the layering of rock strata) varied between 75,000 years and 96 million years. These would be underestimates because they did not take into account the heat produced by radioactive decay. To my knowledge, no scientist has produced a peer-reviewed paper that measures the age of the earth in thousands of years. The references you quote are negative in that they strive to find reasons why the accepted methods should not be believed rather than make a positive contribution to the problem of measuring the age of the earth.

It is remarkable to see the extent to which humans can go to justify a preconceived notion. We have seen Christians make a stand on unjustifiable grounds before; for example when they believed that the sun orbited the earth and that the earth was the centre of the universe. The assertion that the earth can be reliably dated at 6000 years by biblical genealogy alone, and in the face of modern science, is surely rather childish, and it undermines the authority of the same folks who are trying to spread the gospel of Christ….
