Planet earth is just one livable planet out of trillions of planets in trillions of galaxies in the universes out there. Just as we relocate from one address, city, or country, for various reasons - job, education, love, crime, war, freedom, etc, more technologically and spiritually advanced civilizations from other livable planets with the capability for inter stellar travel, move all the time, and at will, for better and less polluted homes. Some settle here, and bring their good or evil knowledge with them. Some find planet Earth uninhabitable, or too primitive, or too polluted, or too corrupt, and move on. Regardless of what our politically insecure and spiritually immature governments think and do, WE ARE NOT ALONE!

Planet earth.
