How long have we been using carbon dating?

twenty thousand years 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.

How long has carbon 14 dating been used?

Can you filter your way through our chemistry quiz? The carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.

How far can radio carbon dating go back?

55,000 years ago The work combines thousands of data points from tree rings, lake and ocean sediments, corals and stalagmites, among other features, and extends the time frame for radiocarbon dating back to 55,000 years ago — 5,000 years further than the last calibration update in 2013.

Why couldnt the fish fossil or dinosaur skull be dated with either C14 or U238?

The fish fossil and dinosaur skull couldnt be dated with either C14 or U238 because carbon can only back date up to 50,000 years and U238 can only back date up to 4.5 billion years. Both the fish fossil and dinosaur skull were older.
