Why do meteorites contain information about the early solar system yet earth does not

See the explanation below.

Explanation:

That the milky way was generated by the explosion of a supernova (giant star in its last stage of life), when the content of this type of stars is based on all the existing materials as possible in the periodic table, in the moment of the explosion, a large amount of energy is released, some of these materials in the blast are left to drift, and the effect of the gravity are joining with each other, forming planets, the material that failed to form planets is orbiting freely low the attraction of the gravitational force of a new rising star, these asteroids have information about the life span of each of them, using a carbon 14 test, scientists can determine what period of formation the galaxy has.

Meteorites are solid that contain a lot of carbon, so tests on them can determine important information from the Galaxy
