Creationist view carbon dating
Other radiometric dating methods such as potassium-argon or rubidium-strontium are used for such purposes by those who believe that the earth is billions of years old.Radiocarbon is not suitable for this purpose because it is only applicable: a) on a time scale of thousands of years and b) to remains of once-living organisms (with minor exceptions, from which rocks are excluded).
The above story is consistent with the Bible, and accounts for fluctuation in C-14 concentrations in the atmosphere that would then be interpreted as older and younger ages than the true ages.
In addition, experiments have been performed that show that the decay rate can be altered under certain laboratory conditions.
(See ) The importance of understanding the true initial conditions of the earth cannot be overstated.
For example, potassium-argon dating (used for longer time scales) assumes that molten volcanic rock is so hot that it forces all the argon gas out before the rock cools.
MYTH #2 Radiocarbon dating has established the date of some organic materials (e.g., some peat deposits) to be well in excess of 50,000 years, thus rendering a recent creation (6 to 10 thousand years ago) impossible.
Some organic materials do give radiocarbon ages in excess of 50,000 "radiocarbon years." However, it is important to distinguish between "radiocarbon years" and calendar years.
The argument is usually boiled down into the following points: 1) Accurate radioactive dating assumes that the decay rate of a radioactive material has not changed over time and is the same today as long in the past. (Although, consider the presence of C-14 in diamonds thought to be millions or billions of years old: https://answersingenesis.org/geology/carbon-14/carbon-14-in-fossils-and-diamonds/ ) (Also, there are restrictions. Sea creatures and animals that eat sea creatures are excluded, since the amount of C-14 in the ocean is much different than the atmosphere.) 4) Dating using Carbon-14 assumes that the fraction of C-14 in the atmosphere had reached a steady state value long ago and has not changed appreciably since then.
2) Dating of objects less than about 50,000 years old is done using Carbon-14, not other isotopes that have much longer half-lives, such as potassium-argon, uranium-lead, rubidium-strontium, etc. (C-14 is assumed to be created by cosmic rays hitting Nitrogen in the atmosphere.) 5) C-14 is absorbed into organisms via respiration or consuming plants that contain it.
In the following article, some of the most common misunderstandings regarding radiocarbon dating are addressed, and corrective, up-to-date scientific creationist thought is provided where appropriate. Radiocarbon is used to date the age of rocks, which enables scientists to date the age of the earth.
Radiocarbon is not used to date the age of rocks or to determine the age of the earth.
