Alien Voyagers could be zipping past the solar system as we write. The fact
we have a hard time finding objects (NEO's) 1km in diameter a few million
miles of earth would indicate that locating a 3-4 meter silent spacecraft
missing the solar system by billions of miles would indicate that its
unlikely we or anyone else would ever detect the craft traversing our region
of space. Even if it came with in a million miles of earth I doubt we'd seen
it.

Is Drake's Theory complete? That is, proposing that an intelligent species
were to arise, and have civilization for a reasonably brief time, I'd
imagine
that they would by extension create artifacts which could outlast them.
Consider Voyager. If our world is destroyed in a nuclear holocaust
tomorrow,
Voyager will still be around a long time from now. Doesn't it follow that
the more advanced and long-lived a theoretical population is, the greater
the
chance of it constructing some sort of artifact which could outlast them?
It follows: if there are or were intelligent species out there for
'trillions of years'... where are their Voyagers?
