Using [[circular logic]] — assuming that decay rates remained constant despite necessarily changing physical characteristics as time approached the origin — Old Earth proponents insist that the Earth is 4.5 billion years old based on an assumption of constancy in [[Potassium-argon dating|Potassium-argon (K:Ar) decay rates]] and other radiometric methods.<ref>Peck, 2000, p.376.</ref>

In 1978, ''Geotimes'' magazine published by American Geological Institute quoted John Eddy, a famous astronomer, who argued  that due to ''“some new and unexpected results“'' scientists could live with bishop Ussher’s 4004 B.C. value for the age of Earth and Sun, ''a fortiori'' since there is not much in the way of [[Scientific observation|observational]] [[Scientific evidence|evidence]] in [[astronomy]] to conflict with his calculations.<ref>{{cite journal |author=John Eddy quoted by R.G.

He has scaled the mountains of ignorance; he is about to conquer the highest peak"'' and ''"as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries."''<ref name="Jastrow">{{cite book
