Apparently Carbon 14 would be no use for Dinosaurs cos it would be all gone by the time we dig it up but fine for later ones.
In an effort to find summit on this I just googled this "How to Date a Fossil"
Apparently Carbon 14 would be no use for Dinosaurs cos it would be all gone by the time we dig it up but fine for later ones.Fossils are petrified, in most cases this means they can't be carbon dated because the original organic material has been replaced by some form of inorganic chemical. In any case, Carbon14 dating is quite unreliable because of the way it can fluctuate, so it is calibrated using dendrochonology, but it has now been discovered that trees can grow more than one ring a year, so that is also flawed and in any case dendro only goes back to about 3,000 BC, which is as far as history goes anyway. Lead and Uranium decay can also be contaminated if they are too closely associated with other minerals.
The point is, we don't know how old the Earth is, we just have evidence and ways of interpreting it. This is no different to Augustine, whose analysis of the available evidence (the historical record) was essentially correct, the Greeks were basically right and the Egyptions really quite wrong.
