The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.
The book explains the basis for this method: “Radiocarbon is continuously created in the atmosphere through bombardment of nitrogen-14 (14N) by neutrons created by cosmic radiation.
pointed out one of the big problems with this dating approach by saying that the past "methods are far from perfect: it is difficult to gain accurate depositional ages for sedimentary rocks, and matters can be further complicated when millions of years of geologic and environmental forces cause erosion of fossil-bearing strata." They highlighted its "success" by contrasting it with the lack of success of prior dating techniques.
It is rare that a weakness in the "millions of years" dating of earth materials is ever mentioned in standard earth science publications.
However, that 18,000-year-old date was based on only a geological analysis of the fossils' surroundings and not on direct analysis of the bones themselves.
And the complexity of the cave's geology initially misled the scientists, says Matthew Tocheri, a paleoanthropologist at Lakehead University in Thunder Bay, Ontario, Canada, and a member of the discovery team.
The theory of evolution has become so ubiquitous in the scientific world today that it even distorts the way geological formations are dated.
However, these dating methods have significant problems that can lead to serious errors of interpretation.
Where igneous rocks are absent, a fossil's "age" is determined by comparing the fossils of one location to those of another, and then comparing those comparisons to charts in books with age assignments provided on the pages.
But in standard studies, no age assignment is ever accepted unless it conforms to the "millions of years" doctrine of evolutionary earth history.
Liang Bua is a cathedral-like cave with a high domed ceiling.
The original excavations, conducted from 2001 to 2004, dug into four regions of the cave, including a couple of sites along its eastern wall, where some fossils were found.
b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.
