Likewise, scientists use radiometric dating to determine the ages of moon rocks, obtained by astronauts.Taken together, these methods give results that suggest an age for our Earth, meteorites, the moon – and by inference our entire solar system – of 4.5 to 4.6 billion years old.Taken as a whole, these data indicate that the Earth’s history extends backward from the present to at least 3.8 billion years into the past.For example, scientists search for and date the oldest rocks exposed on Earth’s surface.

The Cambrian period is conventionally assumed to have begun about 550 million years ago.

Using this technique, scientists could, for example, analyze a sample from Earth’s crust, figure out the quantities of uranium and lead, plug those values along with the half-life into a logarithmic equation, in order to compute the age of the rock.

Over the decades of the 20th century, scientists documented tens of thousands of radiometric age measurements.

Thus radiometric dating methods appear to give evidence that the earth and meteorites are old, if one accepts the fact that decay rates have been constant.

However, there may be other explanations for this apparent age. I also believe that the evidence indicates that the earth has recently undergone a violent catastrophe.

He concluded that Earth was born 20 to 400 million years ago.
