Argon radiometric dating

Since there doesn't seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.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.After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found.These steps help remove as much atmospheric Next, ​the mineral sample is heated to melting in a vacuum furnace, driving out all the gas.A precise amount of argon-38 is added to the gas as a "spike" to help calibrate the measurement, and the gas sample is collected onto activated charcoal cooled by liquid nitrogen.

These dating methods have been under constant improvement for more than 50 years.

The potassium-argon (K-Ar) isotopic dating method is especially useful for determining the age of lavas.

Developed in the 1950s, it was important in developing the theory of plate tectonics and in calibrating the geologic time scale.

The site also must be geologically meaningful, clearly related to fossil-bearing rocks or other features that need a good date to join the big story.

Lava flows that lie above and below rock beds with ancient human fossils are a good—and true—example.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.
