So all you great believers in "goo to you" aka evolution, if the rocks and fossils aren't radio carbon dated, what exactly do they use to ascertain dates?
Please supply some nice clear links so everyone here can have a fighting chance to follow what they're reading ??
I'll start. By google searching "dating rocks evolution", the natural history museum says that there are various ways. The 'actual' dating method is radio carbon dating - either 12C and 14C, and then states that it is only good for rocks to a certain age so alternative dating can be then used. However it doesn't specify what alternatives are used. Hmmm. Why should that be excluded I wonder?

Of course we all know that other dating used can be the likes of uranium-lead dating. But this has the same problem as c14 insofar as it is based on three assumptions.
If you approach it from a world view that there is no God, then you will be looking for evidence of old earth. So you will accept a closed system view of it, meaning there are no external influences such as contamination. This approach also means that you have to insist there were no 'daughter isotopes' - lead-206 and lead-207 - from the very beginning (how can anyone know that since no one was there and it can't be tested or observed in a lab!?). If there were daughter isotopes present then it would support younger earth and so because it doesn't fit the model required, the assumption is held fast to. A belief, you might say!
Then there is the assumption that the rate of decay has no variation. But again, we weren't there billions of years ago to record what it was then and what it is now, so it relies on a certain assumption (a belief, one might say). And if the rate of decay is variable then it supports a young earth.
However we know that other radioactive isotopes can vary - such as radon-222 and silicon-32, and a known possible reason for variation is their proximity to the sun. Not all isotopes behave this way so there clearly are other unknown reasons for this. Other isotopes alter such as Th-228, Rn-22, and Si-32, although these aren't used for dating rocks specifically they still show radioisotope decay is not constant. So why don't scientists give a reason for accepting one isotope is not constant while insisting another one is, when they don't know why some are variable? Perhaps it is because the dates wouldn't tally with old earth.
Can anyone see how these assumptions, or beliefs, determine the results obtained? It's pretty easy really. And the trouble with a society that finds it popular to ditch God on every level, scientists are under as much pressure as anyone else to conform to the popular viewpoint; conform or be ostracised.
Someone earlier mentioned scientists who don't dare swim against the tide, for fear of not advancing in their career or even losing their jobs. Perhaps this could be a legitimate reason for a Christian scientist woman arguing against c14, or maybe she could be a nominal Christian, you know, one of those "Sunday best" type Christians who don't really walk the walk. Who knows but it's for sure there are plenty of possibilities.
I could go on but it's a busy weekend and I could only post this because I was up in the night with my DC!
