Are You An Alien? An alien to Earth is life not of Earth. Some hypotheses suggest that ice was delivered to Earth by comet storms from the Oort cloud during previous collisions of the Milky Way Galaxy with other galaxies in our Local Group. The galaxy collisions scrambled star orbits and passing stars could distort each other’s Oort Clouds, mixing comet populations and throwing comets inward toward the planets. If this is true then some of the water molecules in your body may have originated in another galaxy. Does this mean you are an alien to Earth?
