The Earth was never a star, it was always a planet from the earliest moment that it formed out of smaller objects when the solar system first coalesced out of a giant cloud of interstellar gas. Planets are not like starts. Stars are much larger and are made from very hot gas; planets are much smaller and colder, and in the case of the Earth, are made mostly of solid or liquid substances, rather than gas (although the Earth does, of course, have an atmosphere made of gas).
