"But carbon dating is flawed!
Its half life is 5730 years, and that supports our cause"

from Greydon Square – A Rational Response Lyrics on Rap Genius

Radiocarbon dating, or just carbon dating, is method that uses the naturally occurring radioisotope carbon-14 to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years.

It is used to date organic materials, and the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites.

Half life is the period of time it takes for the amount of a substance undergoing decay to decrease by half.

Ex- There is 100 grams of a substance. If in 7 years, half of the 100 gram substance decays, leaving only 50 grams, that substances “half life” is 7 years.
