How important is the age of the earth to evangelism?

The age of the Earth is 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%). This age may represent the age of the Earth’s accretion, of core formation, or of the material from which the Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
