Why do scientists use carbon dating to prove their theory that the earth is millions of years old when carbon dating only shows for thousands of years?

Carbon dating is a process which unveils the age of a stone or a fossil...bcz the different layers of a stone which is otherwise called oxidation, takes certain thousands of years for its formation, which is revealed by carbon dating...Answered by Quest, 03 Apr '13 11:43 am

Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon 14. This radioactive carbon 14 slowly decays back into normal, stable nitrogen. Extensive laboratory testing has shown that about half of the C-14 molecules will decay in 5,730 years. This is called the half-life. After another 5,730 years half of the remaining C-14 will decay leaving only 14 of the original C-14. It goes from 12 to 14 to 18, etc. In theory it would never totally disappear, but after about 5 half-lives the difference is not measurable with any degree of accuracy. This is why most people say carbon dating is only good for objects less than 40,000 years old. Nothing on earth carbon dates in the millions of years, because the scope of carbon dating only extends a few thousand years. Willard Libby invented the carbon dating technique in the early 1950s. The amount of carbon 14 in the atmosphere today is about .0000765%. It is ass ...moreAnswered by rajan, 03 Apr '13 08:36 am
