Carbon 14 dating is calibrated by dating objects of known age, such as Egyptian artifacts and tree-rings.
In the White Mountains of California there are standing dead trees (bristlecone pines). They each rings. Those rings form sequences. The sequences can be overlapped, to give a continuous tree-ring sequence back some 11,600 years.
By dating individual tree-rings, a calibration curve can be established which corrects for the amounts of Carbon 14 in the atmosphere, which vary slightly.
Using other techniques, such as glacial varves this calibration curve can be extended past 20,000 years.
Now you may not choose to believe in it, but tens of thousands of scientists find it an accurate method of dating.
So please do not tell me that Young Earth Creations is not a science.
Creationism in all of its forms are not science, they are religious beliefs.
Would you be willing to entertain the possibility that all of science is of divine design?
