Creationists often criticize radiocarbon dating in the context of discussions of the age of the earth.

Dates up to this point in history are well documented for C14 calibration.

For object over 4,000 years old the method becomes very unreliable for the following reason: Objects older then 4,000 years run into a problem in that there are few if any known artifacts to be used as the standard.

Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.

Scientists place great faith in this dating method, and yet more than 50% of radiocarbon dates from geological and archaeological samples of northeastern North America have been deemed unacceptable after investigation.

by Helen Fryman Question: What about radiocarbon dating? Response: I asked several people who know about this field. (1.) C14 dating is very accurate for wood used up to about 4,000 years ago.

This is only because it is well calibrated with objects of known age.

While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.

Thus radioactive dating relies purely on assumptions.

After all, this what the archeologist guessed in their published books.
