aliens, monsters and other weird creatures — what if?

Growing up I used to watch lots of science fiction movies and TV shows with aliens, monsters and other weird creatures (lots of black and white “horror” movies, especially with characters like Dracula and Frankenstein). Well I still wonder if there’s life elsewhere in the cosmos.

Maybe earth’s not the only inhabited chunk of rock in the universe. Maybe there are more of us somewhere else. Maybe, just maybe, we’re not his first children, perhaps not even his last. Could this explain the missing link?
