Carbon 14 Dating of Fossils

June, 2017

Organic matter in the fossil record generally dates by carbon 14 (C14) dating to about 20,000 to 40,000 years. Other radioactive dating methods such as potassium/argon (K/Ar), rubidium/strontium (Rb/Sr), uranium/lead (U/Pb), thorium/lead (Th/Pb) and others that are based on decay of longer-lived isotopes often give ages in the millions or hundreds of millions of years for these fossils. Why is this? Why are the dates so different?

Many creationists believe that radioactive decay was faster in the past. However, in this talk I want to concentrate on reasons to believe the C14 dates are more accurate and that they give evidence that all life on earth is very young. If decay rates were faster in the past, then even the C14 dates could be too old.

How Carbon 14 Is Produced and Decays

Carbon 14 is an isotope of carbon with two extra neutrons in the nucleus. It is produced in the upper atmosphere. The rate at which this happens varies to some extent. Perhaps there was less C14 produced in the past, which would imply that even the relatively young C14 dates are too old.

Evidences for a Recent Creation: Part 2

November, 2005

Part I mentioned helium retention in zircons and young carbon 14 dates as evidences for a recent creation and for an acceleration of decay rates in the past. Such an increase in decay rates should have more of an effect on ages computed from isotopes with long half-lives than elements with short half-lives.

Also, alpha decay and beta decay use different processes. Therefore they may not be affected the same amount by an increase in the decay rate. So discordances between alpha and beta decay ages are an evidence of disturbed decay. To sum up, the following are the evidences one would expect from accelerated decay in the past: Carbon 14 ages should be much younger than other isotopic ages like K-Ar, U-Pb, et cetera. Alpha and beta ages should differ. And ages computed from elements with long half-lives should be more affected than ages computed from elements with short half-lives.

Creation Resources and Evidences

April, 2005

Recently I was asked to give a talk on resources available on creation. I expanded the topic to include best evidences for creation. This article is based on that talk. For resources, I will discuss some of the major websites and organizations. Many of these will probably be familiar to you if you have been interested in creation science for a while. For best evidences, I will discuss scripture, the origin of the universe, the origin of life, the origin of species, empirical detection of intelligent causes, and the age of the earth.

Birds-Eye View of Creation Science

February, 2018

There is an expression about not seeing the forest for the trees. Sometimes it is good to step back, and look at the larger picture. With regard to creation science, there are lots of "trees;" we have articles on geology, genetics, chemistry, paleontology, cosmology, botany, etc. But what is the big picture? Let's start at the beginning: the origin of life.

Abiogenesis, the Origin of Life

Regarding the origin of life (without God), or abiogenesis, we realize that this is extremely difficult. No one can explain how this happened using only the known laws of science. How difficult is abiogenesis? One evolutionary biologist has proposed an infinite number of universes in order to help out with the probabilities. 1,2 The clear implication is that in one universe, the origin of life is so unlikely that, for all practical purposes, life could never have arisen. The probability is that low. 

Probability Calculations 

Regarding probabilities, the evolutionist who wrote the book Mathematics of Evolution and who gave the Big Bang its name, stated the odds of getting just some of the requirements for a single cell are trillions of times less likely than getting the single winning lottery ticket if each atom in the universe were a lottery ticket! Yes, the entire universe. And he stated the odds for getting single cells to evolve were trillions of times less than that.

So, we will just assume that life somehow originated. We will simply ignore the problem of how life arose in the first place. But before we move on we will consider one point about the origin of life from non-life.
