Carbon 14 dating not accurate
One reason is the fact that it has a radioactive isotope and second reason is that life is based on carbon compounds.This made age determination of carbonaceous life possible. This is because the fundamental assumptions or axioms, on which a method like carbon dating is based, are only approximately true or accurate.All the physical laws we know have limits of validity.
It is necessary that the dating sample be as uncontaminated as possible, to give it an accurate age.
Lately, the accuracy of this technique has been a matter of debate.
It is doubted due to certain perceived flaws in its fundamental assumptions and ambiguous results.
This dating method is based on comparison of ratios of two carbon isotopes, which are C-12 and C-14. Isotopes are elements with the same atomic number, but different atomic mass numbers. By comparing the amount of radioactive carbon present now, with the amount at the beginning, an age estimate can be made, based on laws of radioactive decay.
Why was carbon chosen for the dating method, out of all the radioactive elements?
Unfortunately the use of dendrochronology to calibrate carbon dating is itself fraught with uncertainties. With further research we may be able to hone the method and increase our confidence in it. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him.
