That's a bit self-important.  

If the universe is teaming with life, but alien civilizations capable
of interstellar travel are exceedingly rare, there would be little
reason for those spacefaring aliens to visit any but the other
advanced alien civilizations.  

We might get the equivalent of an anthropologist ever few million
year, and they would do whatever needed to prevent detection by that
which they study.
