Thus radiometric dating methods appear to give evidence that the earth and meteorites are old, if one accepts the fact that decay rates have been constant.

However, there may be other explanations for this apparent age. I also believe that the evidence indicates that the earth has recently undergone a violent catastrophe.

For isochrons, which we will discuss later, the conditions are different.

If these conditions are not satisfied, the error can be arbitrarily large.

We are told that of all the radiometric dates that are measured, only a few percent are anomalous.

This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.

In two half-lives, half of the remainder will decay, meaning 3/4 in all will have decayed.

In general, in n half-lives, only 1/(2^n) of the original parent material will be left.

Even the creationist accounts that I have read do not adequately treat these issues.

On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.

We are told that these methods are accurate to a few percent, and that there are many different methods.

In order to use these methods, we have to start out with a system in which no daughter element is present, or else know how much daugher element was present initially so that it can be subtracted out.

We also need to know that no parent or daughter has entered or left the system in the meantime.
