Old Earth advocates rely on one flawed assumption to the exclusion of other evidence, similar to how an investigator may mistakenly rely on one eyewitness's opinion to the exclusion of all else. In fact, eyewitness testimony is proven to be less reliable to than other indicators, just as the assumption by Old Earth proponents that the [[Radiometric dating|rate of radioactive decay]] has always been constant is flawed. In fact, a large number of physical processes, such as neutron capture and fluctuations in solar radiation, can affect the rate of radioactive decay of elements in the Earth's crust and render radioactive dating measurements unreliable with errors up to 5%, depending upon the specific methods used.<ref>http://www.sciencedirect.com/science/article/pii/S0899536205000138#bib6</ref> Even so, such an error will not cause a calculation of the age of the Earth based on radiometric dating to be off by up to five [[order of magnitude|orders of magnitude]]. | Old Earth advocates rely on one flawed assumption to the exclusion of other evidence, similar to how an investigator may mistakenly rely on one eyewitness's opinion to the exclusion of all else.
