Perhaps the earth was made from older pre-existing matter, or perhaps decay rates were briefly faster for some reason. Geologic time is divided up into periods, beginning with the Precambrian, followed by the Cambrian and a number of others, leading up to the present.
We are told that these methods are accurate to a few percent, and that there are many different methods.
For potassium 40, the half-life is about 1.3 billion years.Even the creationist accounts that I have read do not adequately treat these issues.At the start, let me clarify that my main concern is not the age of the earth, the moon, or the solar system, but rather the age of life, that is, how long has life existed on earth.However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over 500 million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.If these dates are correct, this calls the Biblical account of a recent creation of life into question.
The universe is full of naturally occurring radioactive elements.
