Earth has a favorable distance from the Sun, where temperatures are neither too hot nor too cold and water is in the liquid phase; also a powerful magnetic field that shields somewhat from harsh effects of solar wind (which could potentially dry the planet's surface up somewhat like Mars); also an abundance of raw material particular the "organic" elements carbon, phosphorus, oxygen, nitrogen, hydrogen, sulfur; sufficient mass to retain an atmosphere; an atmospheric composition favorable to life; and of course abundant water.
