Aliens-wanderers
According to scientists in the sphere of the UFO, our planet is usually visited by Aliens-wanderers. These aliens have no exact place of living. In fact this race is similar to nomad peoples of our planet.
Aliens-wanderers is maybe the most developed civilization in the universe, they have equipment, the technology of which is unknown to any cosmic civilization including humanity. They are able to do miracles.
This race has wide knowledge and valuable resources. But at the same time this race likes to make the contacts with all kinds of civilization teaching them and helping them. But it is not done for free. Usually their help is similar to deals.
Deals with aliens are especially profitable but at the same time very unsafe. This race is very cunning and may deceive people. Contact with them is good when this civilization gives presents. For example, aliens may exchange the three year reserve of resources of Earth into the masterpiece Mona Lisa. But they often lie, that is why it is necessary to be very careful with this civilization.
Wanderers may take human beings to space to travel with them but only if a person wants it. But in few years they usually return the person to Earth as human beings start to suffer and to miss their families and their planet.
