It was just another planet created from rocks colliding, but planet Earth is the perfect distance from the sun to make it not too cold and not too hot. This condition is ideal for life. Earth is the only planet so far discovered to sustain life.
Earth is the only habitable planet in our solar system. As for the rest of the universe, it's highly probable that there are planets that can sustain life but compared to the billions of other objects in that vast emptiness, it's a difficult task to even find any.

If the environment was very similar to Earth, yeah. Otherwise, no.
