Radioactive dating fossils isotopes used
They will argue that the clock was not reset if the age is too old, or that isotopes were selectively removed if the age turns out to be too young.
In the study on the Hawaii lava flow cited above, it was argued that entrapment of excessive amounts of argon gas had made the samples appear older than they were.
Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.
The current high rate of entry might be a consequence of a disturbed post-Flood environment that altered the .
Specimens would then look much older than they actually are.
d) Even if the rate of decay is constant, without knowledge of the exact ratio of carbon-12 to carbon-14in the initial sample, the dating technique is subject to question.
While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.
Thus radioactive dating relies purely on assumptions.
