If it turns out that there is life in the ocean of Europa, which has
existed for something like four billion years, it supports the general
idea of "random but inevitable" theories of Abiogenesis.

_Remembrance of Earth's Past_ has an interesting take on the whole
notion behind an "empty" universe.  It's a tedious read (mainly for
me coming from a non-chinese culture... just keeping track of the
characters is difficult) but has some good ideas to chew on at its core.

 My guess: The Universe is mammoth, the technological and energy requirements of even short-distance interstellar travel are immense, the lifespan of technological civilizations is highly time-limited before such a civilization destroys itself, technological civilizations are very rare to begin with, and no technological civilization ever survives long enough to attempt it.

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.
