So recently I stumbled across a video that was trying to prove the earth was 6000 years old but he had a point that I didn’t really know how to debunk, the point was that we found diamonds with c-14 and c-14 is gone after around 50,000 years, the diamonds could not have been contaminated from the atmosphere as the diamonds are underground therefore the earth cannot be 4.6 billion years old. Now geology is not my specialty but I know there has to be something I’m missing. Ik this one piece of supposed evidence doesn’t debunk all the evidence from geology that the earth is billions of years old but it’s bothering me that I can’t figure out a debunk.
