It's also not a problem that geologists say that the sedimentary layers of rock took millions of years to form, since there are many evidences that the great geological formations on earth were formed rapidly and catastropically, as in the Biblical flood or subsequent catastrophic events.For example, there is too little erosion between the geological layers for them to have taken millions of years to form.This millions of years time scale is based on radiometric dating of fossil-bearing layers of rock.This teaching of long ages for life on earth has led some Christians to question and even abandon their belief in the Bible, since a literal reading of Scripture is not consistent with the belief that life has existed on earth for millions of years.

When the carbon dioxide, containing C14 as well as stable C12 and C13, is taken in by plants it is no longer exposed to the intense cosmic ray bombardment in the upper atmosphere, so the carbon 14 isotope decays without being replenished.Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more than 50,000 years old.other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.

Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.

Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.
