Dating the rocks
Despite the fact that there are many scientific problems with radiometric dating, there is a more significant problem.
The Bible gives a much different picture and explains that relying on man’s reasoning is foolishness.
Far from being data, these dates are actually interpretations of the data.
As discussed before, the assumptions influence the interpretation of the data.
Knowing this first: that scoffers will come in the last days, walking according to their own lusts, and saying, “Where is the promise of His coming?
For since the fathers fell asleep, all things continue as they were from the beginning of creation.” For this they willfully forget: that by the word of God the heavens were of old, and the earth standing out of water and in the water, by which the world that then existed perished, being flooded with water.
The reason this age may not be a true age—even though it is commonly called an absolute age—is that it is based on several crucial assumptions.
Determining the relative age of a rock layer is based on the assumption that you know the ages of the rocks surrounding it.
If certain things are known, it is possible to calculate the amount of time since the parent isotope began to decay.
For example, if you began with 1 gram of carbon-14, after 5,730 years you would be left with 0.50 g and only 0.25 g after 11,460 years.
The starting isotope is called the parent and the end-product is called the daughter.
The time it takes for one half of the parent atoms to decay to the daughter atoms is called the half-life.
