In some cases these astronomical cycles in rock appear to have been laid down over some 25 million years (and radiometric dating puts the absolute age of the rock at some 200 million years).Dating Anomalies Here we outline a few dating methods or 'clocks' that present a dating anomaly when referenced to the widely accepted OE age of 4.6 billion years. At the outset we note C-14 cannot be used to directly date the earth for the simple reason that the unstable C-14 isotope has a half-life of just 5,730 years.This challenge is mainly headed by Creationism which teaches a young-earth (YE) theory.A young earth is considered to be typically just 6,000 years old since this fits the creation account and some dating deductions from Genesis.Most people accept the current old-earth (OE) age estimate of around 4.6 billion years.This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution.

The implication is that this organic material was either contaminated by new C-14, or it was buried much more recently and OE dating methods are suspect.The technique gave 90 million years, but took no account of the non-constant erosion rate, or the loss and recycling of salt, or the fact that salt is obtained from other sources as well as continents.More recently, work has been done on ocean sediments [S. This suggests that, given the current annual rates of erosion (some 27.5 billion tons), all earth's continents would be delivered into the oceans in just 14 million years.In other words, half of the radioactive isotope in a sample would have decayed to Nitrogen-14 (N-14) in just 5,730 years.C-14 dating of carbon-bearing materials is therefore limited to roughly 50,000 years.
