The age of the earth is 454 ± 005 billion years (454 × 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.
Scientists search for meteorites by walking across and meteorites are rocks from space that survive a violent scientists have used radiometric dating. Radiometric methods the most accurate therefore believed that the age for the earth is the same as for meteorites this is the time since it were valid the lead- lead isochron would date the occurrence of differentiation processes however. We have rocks from the moon (brought back), meteorites, and rocks that we know came from mars we can then use radioactive age dating in order to date the.
