'''The following answer, which is factually inaccurate, was taken almost verbatim from http://contenderministries.org/evolution/carbon14.php. I will leave it here in it's entirety but add in notations to better the question asker's understanding of the subject.'''

One problem is that it (Carbon-14 Dating) may not be accurate because it relies on several assumptions (or guesses) that have not been proven (using the scientific method) to be true.


1. It assumes the rate of decay of carbon-14 has remained constant over billions of years.
''Radioactive decay rates do not change. Ever.''

2. It assumes the rate of carbon-14 formation has remained constant over billions of years.

''False. See my notation after #3.''

3. It assumes the concentrations of carbon-14 and carbon-12 have remained constant in the atmosphere over billions of years.''

''

''This is false. When scientists perform carbon dating they use a calibration curve (http://en.wikipedia.org/wiki/Radiocarbon_dating#The_need_for_calibration) to compensate for varying levels of carbon 14 in the atmosphere caused by variations in the rate of carbon-14 formation. They do NOT assume the levels of carbon-14 have been constant forever.''

4. It assumes the amount of carbon-14 being presently produced had equaled the amount of carbon-12, so that it had reached a "balance" that does not change.

''This is not only false but completely made up.'''''

'''

5. It assumes all plant and animal life utilize carbon-14 equally as they do carbon-12.

''It assumes no mechanism for straining out some or all of carbon-14 and using only carbon-12. This is because no one has ever show such a mechanism to exist.'' ''

''''The reason long term carbon dating (such as for determining the age of the earth) is not accurate is that we have no idea what the carbon-14 levels were past a certain point.

''

''for the short term (less than 45,000 years) carbon dating is indeed accurate due to calibration curves allowing scientists to compensate for varying levels of carbon-14 in the atmosphere. '' So its like a blind date its not gonna go well now is it da
