Non radiometric dating methods
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).
Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.
his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.
"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.
Third, evolution of living organisms into more advanced life forms by natural selection or mutations.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).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.
