Don’t think that there are others out there...but...
They are looking at our galaxy and wondering if life exists on our planet.
They are still a bit backward and do not have the capability to send signals to us.
They are way advanced beyond us and their signals have been lost in the past. They are trying to resolve their own financial problems and no longer provide funds for space exploration.
They are at our level and still trying to figure out how to govern without taking out the job creators.
LOL!!
...A request, if there are UFO's visiting us, don't bring weapons. Let the aliens land, they might be here to pick me up.
They sent me this postcard, "We're on the way. Don't forget your toothbrush."
Perhaps they came as honey bees and are still here, living among us
or
Like Douglas Adams said, they came as dogs and no one paid them any attention
