Question

Describe why estimating the age of the Sun can give an approximate age of the Earth.

Answer 1

Since the planets formed not too longer than the sun, just use the sun's estimate, then see how far you could go back in history to see how old the sun is and compare it to Earth's since the age is not too far apart. "not a real answer just trying to help"

Answer 2

The sun is a main source on providing life on earth. So if it were to be estimated it would be the same as the earth's life span because when the sun was born life on earth was also born simultaneously. <span />
