Based upon radiometric dating the age of the earth is
Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.6 billion years.
Here we will describe just two types of evidence for an old Earth and two types of evidence for an old universe; more types can be found under further reading.
Geology for Environmental Scientists Geology for Environmental Scientists. Absolute age dating is based upon the decay of radioactive. In recent years the Jehol Group of China has provided evidence of catastrophic burial that contradicts current evolutionary hypotheses.
