The excavator might employ relative dating, using objects located stratigraphically (read: buried at the same depth) close to each other, or he or she might compare historical styles to see if there were similarities to a previous find.But by using these imprecise methods, archeologists were often way off.I once heard of a trick played on scientists by some anti evolutionists.The scientists subsequently dated a piece of LIVE coral as 14,000 years old.Most laboratories measure radiocarbon with a very sophisticated instrument called an accelerator mass spectrometer, or AMS.It is literally able to count carbon-14 atoms one at a time.3 This machine can theoretically detect one radioactive carbon-14 atom in 100 quadrillion regular carbon-12 atoms! AMS instruments need to be checked occasionally, to make sure they aren’t also “reading” any laboratory contamination, called background.So if fossils are really millions of years old, as evolutionary scientists claim, no carbon-14 atoms would be left in them.
It’s a dilemma for evolutionists, who believe the rocks are millions of years old. Radiocarbon (carbon-14) is a very unstable element that quickly changes into nitrogen.
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.
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.
