This challenge is mainly headed by Creationism which teaches a young-earth (YE) theory.

A young earth is considered to be typically just 6,000 years old since this fits the creation account and some dating deductions from Genesis.

The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.

This atom is not stable, and will break down, releasing nuclear energy in the process.

This is consistent with the assumption that each decay event is independent and its chance does not vary over time.

Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale.

The normal carbon atom has six protons and six neutrons in its nucleus, giving a total atomic mass of 12.Radiocarbon dating is frequently used to date ancient human settlements or tools. It is a stable atom that will not change its atomic mass under normal circumstances.Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.This collision is less destructive than the initial collision that produced them.And OE Christians (theistic evolutionists) see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating - A Christian Perspective.This is the crucial point: it is claimed by some that an old earth supports evolutionary theory and by implication removes the need for biblical creation.Radioactive carbon (Carbon 14) is formed in the upper atmosphere as a byproduct of cosmic radiation.Cosmic rays are positively charged atoms moving at enormous speeds.
