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.Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.Recent research by a team of creation scientists known as the RATE (arth) group has demonstrated the unreliability of radiometric dating techniques.Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.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.

Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements.

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.

Most radiometric dating techniques must make three assumptions: The major problem with the first assumption is that there is no way to prove that the decay rate was not different at some point in the past.

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.
