Before radiocarbon dating
The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1.5 billion years old.
The helium still locked in the samples was studied as well as the rate at which the helium diffused from the rock.
When it comes to determining the age of stuff scientists dig out of the ground, whether fossil or artifact, “there are good dates and bad dates and ugly dates,” says paleoanthropologist John Shea of Stony Brook University.
The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results.
Atmospheric nuclear weapon tests almost doubled the concentration of Radiocarbon dating, also known as the C14 dating method, is a way of telling how old an object is. This makes it possible to tell the age of substances that contain carbon. Dates obtained are usually written as before present ('present' is 1950).
Carbon has different isotopes, which are usually not radioactive.

The New Zealand curve is representative for the Southern Hemisphere, the Austrian curve is representative for the Northern Hemisphere. C is the radioactive one, its half-life (time it takes to reduce its radioactivity by half) is about 5,730 years.
The material on this site is targeted to a broad spectrum of scientific, religious and social movements.As our knowledge continues to grow, what we know continues to be in agreement with Scripture.Radiocarbon ages less than 3,500 years old are probably accurate.In 1960, he was awarded the Nobel Prize in Chemistry for this work.He first demonstrated the accuracy of radiocarbon dating by accurately estimating the age of wood from an ancient Egyptian royal barge of which the age was known from historical documents.
