There are two primary problems with both techniques:
1) It's assumed that the increase or decrease in radioactivity is a
constant, and we have NO way to prove that it is.
2) The ONLY factor (written history) which can be used to calibrate either
technique is not accurate itself.
There's abundant scienfic evidence that increases and decreases in
radioactivity are not constant. As just one example, recent measurements of
the changes in the strength of the Earth's magnetic field suggest that the
magnetic field may have been so strong just 5,000 years ago that space
radiation may not have even been able to enter the atmosphere.
Obviously this would throw the calibration way off. On top of that, the
assumption that any existing written document is older than 2,000 years is
an ASSUMPTION, so the calibration of organic matter that's associated with a
2,000 year old written document is based exclusively on an ASSUMPTION that
cannot be proven with any scientific validity.
A small error in that ASSUMPTION would throw off the extrapolation by
thousands or tens of thousands of years.
The third problem, of course, is that 2 people become 6 billion people in a
big hurry. At the rate of growth of the US, with wars, abortion, and the
pill, it would take only 1,500 years to go from two people to the current
world population of 6 billion http://christianparty.net/population.htm
