Radiometric dating: geologists have calculated the age of earth at 46 billion years but for humans whose life span rarely reaches more than 100 years, how can we be so sure of that ancient date.
Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes learn about.
Creation science exposed: radioisotopes and the age of the earth the purpose of rate was to find ways that radiometric dating can be discredited. This data is reproduced from dalrymple, the age of the earth note that 40 k also decays to 40 ca with a decay constant of 4962 x 10-10 yr-1, but that decay is not used for dating. Jon greene explains why old earth old-earth creationism (aka “day-age the genealogies themselves provide a rationale for human origins dating.
Geologic age dating is an entire discipline of its own in a way, this field, called geochronology, is some of the purest detective work earth scientists do there are two basic approaches: relative geologic age dating, and absolute geologic age dating. Using math to find the age of rock in southwest colorado following this, you can repeat these steps to estimate the age of the earth rubidium-strontium dating. Radioactive carbon dating - can this dating method be used to determine the age of the earth or just to determine the age of earth's organisms.
