Because the exact amount of time this accretion process took is not yet known, and the predictions from different accretion models range from a few million up to about 100 million years, the exact age of Earth is difficult to determine.It is also difficult to determine the exact age of the oldest rocks on Earth, exposed at the surface, as they are aggregates of minerals of possibly different ages.His father, James Rutherford, was a farmer from Scotland and his mother, Martha Thompson, was a schoolteacher from England.Ernest was the fourth of the 12 children his parents brought up in New Zealand, and he was blessed with both high intelligence and a talent for sports, particularly rugby football.material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

It is hypothesised that the accretion of Earth began soon after the formation of the calcium-aluminium-rich inclusions and the meteorites.

Early attempts at establishing an absolute time scale utilized the following concepts: declining sea levels, cooling of the Earth, cooling of the Sun, Earth tidal effects, sediment accumulation, and changes in ocean salinity.

Using changes in Earth's temperature or the Sun's use of energy failed because energy from nuclear reactions was unknown.

When Rutherford announced his findings it soon became clear that Earth is millions of years old.

These scientists and many more after them discovered that atoms of uranium, radium and several other radioactive materials are unstable and disintegrate spontaneously and consistently forming atoms of different elements and emitting radiation, a form of energy in the process.
