How old is the earth based on radiometric age dating

how old is the earth based on radiometric age dating-38

These isotopes have longer half-lives and so are found in greater abundance in older fossils.Some of these other isotopes include: back to the last global catastrophe (i.e.

These long time periods are computed by measuring the ratio of daughter to parent substance in a rock, and inferring an age based on this ratio.This belief in long ages for the earth and the evolution of all life is based entirely on the hypothetical and non-empirical Theory of Evolution.All dating methods that support this theory are embraced, while any evidence to the contrary, e.g. Prior to radiometric dating, evolution scientists used index fossils a.k.a. A paleontologist would take the discovered fossil to a geologist who would ask the paleontologist what other fossils (searching for an index fossil) were found near their discovery.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.Also, many fossils are contaminated with carbon from the environment during collection or preservation procedures.This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.

Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. The half-life of carbon-14 is approximately 5,730 years. dinosaurs the evolution alleges lived millions of years ago.

As stated previously, carbon dating cannot be used on artifacts over about 50,000 years old.

These artifacts have gone through many carbon-14 half-lives, and the amount of carbon-14 remaining in them is miniscule and very difficult to detect.

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.

This restriction extends to animals that consume seafood in their diet.

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
