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.

Many dating methods seem to give about the same ages on meteorites.

Potassium is about 1/40 of the earth's crust, and about 1/10,000 of the potassium is potassium 40.

Uranium decays to lead by a complex series of steps. Thus we obtain K-Ar dating, U-Pb dating, and Rb-Sr dating, three of the most common methods.

I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions.

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

Potassium is present in most geological materials, making potassium-argon dating highly useful if it really works.

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.
