Should we trust radiometric dating? This is Ken Ham, on a mission to call the church back to God's word. Secular scientists often claim to be able to date rocks to millions of years using radiometric dating. Now, unstable atoms in rocks slowly decay into stable atoms. Since scientists know how long the decay takes, well, they measure the number of stable atoms and calculate how long it took for them to form. But this process rests on assumptions that can't be verified about the past. One assumption is that all the stable atoms are the result of decay. But we know this isn't always true with rocks that we've watched form. So why should we assume it's true for rocks we couldn't watch? Instead of relying on unprovable assumptions, we should trust God's word to give us the real age of the earth. You can learn more about radiometric dating and the Earth's age at answersingenesis.org.
