There are places in this universe that are very different from the planet you and I inhabit. Take, for example, the planet Yerka in NGC 5194 (the Whirlpool Galaxy). Yerka started its existence as a gas giant. A close interaction with another gas giant in the same system sent it into an orbit near the Goldilocks zone of its star. Then the star went supernova and collapsed into a pulsar. This stripped away all of the gasses of the planet, leaving behind only the rocky core. Eventually the pulsar stopped and became a neutron star. Bombardment from comets that were disrupted by the supernova eventually delivered enough gasses and water that life arose on the planet.
