Determining a person’s age at death based on their skeleton is the same if they died 3,000 years ago or 30 years ago.
A thought and a contrarian geological viewpoint:
We cannot determine the age of a rock w/any degree of accuracy by radio-carbon dating for the very basic reason that we do not know the radioactive elements present in the rock at formation nor have we been able to monitor the way these elements have changed, if at all, over time.
While the Greeks gave us eternal Laws and Rules in Mathematics and Physics; as well as the likes of Copernicus, Galileo, Newton and Von Leibniz, among other giants; we moderns have produced Theories such as Evolution and Relativity.
It’s obvious to me that there is an inverse relationship between the rigor of the scientific proof and the zealotry of its acolytes.
