That wouldn't explain why there are no *signs* of intelligent life. *We* can't (yet) travel interstellar distances in single lifetimes but I'm sure anyone with technology comparable to ours would be able to *detect* our presence (given that we seem to make no attempt at "hiding") _If the Universe Is Teeming with Aliens ... WHERE IS EVERYBODY?_ gives some interesting takes on the Fermi paradox.
