Life spaced out

[H]

Stephen Hawking theorized three possible options to whether there is extraterrestrial life.
One option is that there likely isn't any.
A second option is that there has been intelligent life elsewhere -- but when it gets smart enough to send signals into space, it also is smart enough to make destructive nuclear weapons.
Hawking said he prefers the third option:
"Primitive life is very common and intelligent life is fairly rare."
He added, "Some would say it has yet to occur on earth."

Thank you, Stephen, for adding that quip: we are not alone and we like to be repeated. Also, being smart is not necessarily being intelligent.
