That's going by the assumption that a planet has evolved INTELLIGENT life or not. It's already enough of a crapshoot for any sort of life to evolve anywhere! For the conditions to be right for intelligent life to come into existence on another planet, the chances aren't great. Then we have no idea how big the universe is either, so if intelligent life has evolved anywhere else in the universe, probablity would suggest it's VERY far away from us.
