Radiometric dating a christian perspective
The taxman in our analogy would represent the radioactive decay of the C-14.In the analogy, the taxman visited every 500 years.When these have been understood we will cross examine them in the light of scientific evidence and see how long life on our Earth has been here.If the evidence points to less than 23,000 years as Bible Students believe, then we can conclude that the 7,000-year creative day is correct.The first visit, he takes 10 dollars, exactly half of the 20 dollars that was originally in the dead mans pockets. Since there is now 10 dollars left, he takes five dollars.Another 500 years passes by and there is the taxman again!In the case of fossils, the adding of the 5 dollars would be like finding a fossil with a lot of limestone on it. Going back to the dead man, the way to tell if someone had placed that 5-dollar bill is easy.You see, once the man died, the taxman came and sewed the pocket of his pants shut with such good thread that no one could undo the sewing job but him.
Just like if a different taxman came and counted that five-dollar bill in with the original twenty!C-12 levels need to be verified as constant over the last 50,000 years or so.Going back to our analogy, this would be like seeing a new dead person with the 20 dollars in his pocket.In the case of C-14, half of it goes away in 5,730 years, leaving the fossil with half of the original amount.Eventually, the small amount of C-14 in a fossil is no longer a good indicator of age because there is so little left.
