Other methods scientists use include counting rock layers and tree rings. This age is computed under the assumption that the parent substance say, uranium gradually decays to the daughter substance say, leadso the higher the ratio of lead to uranium, the older the rock must be.

Geologists assert that generally speaking, older dates are found deeper down in the geologic column, which they take as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older. Carbon cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.

This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.

This is some finite point in the future. Carbon has a half life of years, meaning that years after an organism dies, half of its carbon atoms have decayed to nitrogen atoms.

Libby began testing his carbon — 14 dating procedure by dating objects whose ages were already known, such as samples from Egyptian tombs.

When scientists first began to compare carbon dating data to data from tree rings, they found carbon dating provided "too-young" estimates of artifact age. Some of these radiocarbon atoms find their way into living trees and other plants in the form of carbon dioxide, as a result of photosynthesis.

Such a scenario does not answer all of the questions or solve all of the problems that radiometric dating poses for those who believe the Genesis account of Creation and the Flood.

Carbon dating cannot be used on most fossils, not only because they are almost always allegedly too old, but also because they rarely contain the original carbon of the organism that has been fossilized. The half-life of carbon is approximately 5, years. Work that puts our experts years ahead of the game; Japanese lake holds the key.

Carbon, Radiometric Dating and Index Fossils. The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.
