It is shown that the claims for a great age of the Earth, seen so often in uniformitarian literature, are obtained by selecting arbitrarily certain processes by which to attempt to judge the age of the Earth, and ignoring others which have, a priori, as great a likelihood of being reliable. As a matter of fact, most of the possible ways of estimating the age of the Earth give results much less than those demanded by uniformitarian theorists. Of 74 possible ways of determining the age of the Earth considered here, about one-third give results of no more than 10,000 years. Even these results, in many cases, are upper limits; moreover the nature of the process involved is often such that the results are inherently likely to give too great an age.
