Is carbon dating a theory or fact

The shells of live freshwater clams can, and often do, give anomalous radiocarbon results.

However, the reason for this is understood and the problem is restricted to only a few special cases, of which freshwater clams are the best-known example.

Even a hypothetical sample containing absolutely no radiocarbon will register counts in a radiocarbon counter because of background signals within the counter.These two measures of time will only be the same if all of the assumptions which go into the conventional radiocarbon dating technique are valid.Comparison of ancient, historically dated artifacts (from Egypt, for example) with their radiocarbon dates has revealed that radiocarbon years and calendar years are not the same even for the last 5,000 calendar years.If this water is in contact with significant quantities of limestone, it will contain many carbon atoms from dissolved limestone.Since limestone contains very little, if any, radiocarbon, clam shells will contain less radiocarbon than would have been the case if they had gotten their carbon atoms from the air.

Some may have mistaken this to mean that the sample had been dated to 20,000 radiocarbon years.
