Last man sitting - everybody else is dead. The only things living are the sea creatures... Aliens melted the polar icecap and are destroying all vestiges of human life and habitation. the only thing surviving is a radio station, designed and invented by the sitting man, which is sending out a message of help to the universe... the pyramid, which is protected by a forcefield.
We are stuffed!
