We do actually know of dead alien civilizations.  The Albion, the Ennead, and many others died two thousand years ago.  They were very thorough when it came to ending each other in that old war.  But they were thousands of lightyears away.  The light of the stars that watched them die has not yet reached Earth.  It is amazing to think of how vast the galaxy is.  We have explored such a small percentage of it.
