Besides the aforementioned items, the amount of cosmic radiation in the past, and in particular the amount reaching the atmosphere, may have been dramatically different.
If one were to believe the Bible, the earth was surrounded by a layer of water vapor between Creation and the Flood.
The Carbon-14 Dioxide is then utilized by plants during their normal metabolism.
Even a sealed aquarium has sunlight, X-rays, Gamma Rays, ultra-violet light, etc. These variations cause individual organisms to absorb or reject Carbon-14 at different previously published radiocarbon dates must be corrected or mathematically weighted to correct the dates from the published dates to the actual dates.50,000 years it may be seen that the method is based on many false assumptions.For some reason, which I have not yet figured out, at least one person per week has been asking me about the Carbon-14 Radiometric Dating Technique.They want to know if it is accurate or if it works at all.Worse still, sometimes they want to know how evolutionists use Carbon-14 to date dinosaur fossils!Radiometric Dating Technologies are presented to the public by evolutionists as utterly reliable clocks for dating earth rocks or biological materials.There are more than 80 such technologies that are claimed to work.
