Bible and radiocarbon dating
Some clams were dated as having died 50,000 years ago, and they were still alive!
Many Middle Eastern artifacts, preserved under ideal conditions, were consistently giving dates wrong by 20%. Let's look critically at assumption 2, that nothing else affects the ratio in a dead organism.
It is better in that an individual bristlecone pine can live for 2,000 years.
In Egypt, Assyria, Babylonia, and Sumeria, there are "king lists" of who reigned and for how long.Now trees shed their leaves in the fall, and the leaves that fall in a lake form a thin layer at the bottom.This happens annually, and thus very thin annual layers are deposited. More snow is deposited in summer, when the air is wetter, than in winter.Still others did this in Ireland, and others in England.Finally American researchers did this with bristlecone pine trees in Arizona.
