Different civilizations and religions have different methods of dating.However, carbon-14 dating offers something particularly valuable, called absolute dating, which is the age of the substance before the current time.Due to the way the sunlight reacts with the atmosphere, it is also taken in by respiration. From this science, we are able to approximate the date at which the organism were living on Earth.This method is based on the idea of radiative decay of Carbon-14 isotopes over thousands of years.

Scientists have concluded that very little change has occurred in the ratio of Carbon-12 to Carbon-14 isotopes in the atmosphere meaning that the relationship between these two should be very similar to how they remain today.

Carbon-14 is constantly be generated in the atmosphere and cycled through the carbon and nitrogen cycles.

Once an organism is decoupled from these cycles (i.e., death), then the carbon-14 decays until essentially gone.

Carbon- 14 is created when a neutron is excited by a cosmic ray, and then that neutron collides with a nitrogen atom.

The carbon isotope is when absorbed by plants through photosynthesis and consumed by animals.
