Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.These use radioactive minerals in rocks as geological clocks.The atoms of some chemical elements have different forms, called isotopes.To get to that point, there is also a historical discussion and description of non-radiometric dating methods.The example used here contrasts sharply with the way conventional scientific dating methods are characterized by some critics (for example, refer to discussion in "Common Creationist Criticisms of Mainstream Dating Methods" in the Age of the Earth FAQ and Isochron Dating FAQ).For a man who does not believe in a miracle, a slow miracle would be just as incredible as a swift one."*G. Chesterton (1925)."The theory of evolution gives no answer to the important problem of the origin of life and presents only fallacious solutions to the problem of the nature of evolutive transformations . We are condemned to believe in evolution, but we will always search for a suggestion concerning the methods of transformations . Perhaps we are now in a worse position than in 1859 because we have searched for one century and we have the impression that the various hypotheses [of how evolution could have occurred] are now exhausted.

This is different to relative dating, which only puts geological events in time Most absolute dates for rocks are obtained with radiometric methods.These break down over time in a process scientists call radioactive decay.Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. The half-life of carbon-14 is approximately 5,730 years. dinosaurs the evolution alleges lived millions of years ago."In a billion years [from now], it seems, intelligent life might be as different from humans as humans are from insects . To change from a human being to a cloud may seem a big order, but it's the kind of change you'd expect over billions of years." Freeman Dyson, Statement made in 1986, quoted in Asimov's Book of Science and Nature Quotations, p. [American mathematician.]"Slowness has really nothing to do with the question.An event is not any more intrinsically intelligible or unintelligible because of the pace at which it moves.
