If aliens land on Earth, we are in a load of trouble. Humans have not traveled beyond our own moon yet. Since there is no intelligent life in our solar system, the aliens must have traveled from a VERY long distance. Any species that can travel from one galaxy to another and land on a planet there is far beyond us in technology. It would be like showing an airplane to a person from ancient Greece.
It's always been a head scratcher to me that people with such intellect would be so into senseless, mass murder.
