I have always believed in life in other worlds (UFO's) probably because my father claims to have seen one as a young man and because the universe is so vast.
I'm sorry, but this is one of my pet peeves.
Unidentified Flying Object means exactly that --
unidentified. By calling it an alien you are claiming to have identified it. I would like to know how you make the huge leap from "I don't know what it is" to "it's an alien."
