Anything else compared to this artifact is assigned an age range based on the range that was initially assigned to the artifact that it is being compared to. “The components of a circular argument are often logically valid because if the premises are true, the conclusion must be true.” However, “the premises are just as much in need of proof or evidence as the conclusion, and as a consequence the argument fails to persuade.” Far from being exact or reliable, these methods are open to major error.
The good dates are confirmed using at least two different methods, ideally involving multiple different independent labs for each method to cross-check results.
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.
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 article explains, “Think of it as ordering rather than dating.” Basically, scientists could only determine where an item belonged within a particular sequence (think layers of time represented by different sediments or rocks).
Scientists could, for example, say that one particular item is older or younger than another item based on these relative methods, but they could not assign a numerical age to the items.
