Unfortunately, the age cannot be computed directly from material that is solely from the Earth.

There is evidence that energy from the Earth's accumulation caused the surface to be molten.

It looks like this: Most of the other measurements for the age of the Earth rest upon calculating an age for the solar system by dating objects which are expected to have formed with the planets but are not geologically active (and therefore cannot erase evidence of their formation), such as meteorites.

This value is derived from several different lines of evidence.And from the slope of the line we can compute the amount of time which has passed since the pool of matter became separated into individual objects.See the Isochron Dating FAQ or Faure (1986, chapter 18) for technical detail.The most direct means for calculating the Earth's age is a Pb/Pb isochron age, derived from samples of the Earth and meteorites.This involves measurement of three isotopes of lead (Pb-206, Pb-207, and either Pb-208 or Pb-204).
