I think the really significant term in the Drake equation is the question of time overlap between our civilization and any civilizations in other star systems.
In other words, the likelihood that they either lived before or (will live) after us is overwhelming, since the time scale of the universe is so vast compared to the time scale (with our one known example) of a civilization.
Our timeline is like the blink of an eye, compared to the age of the universe. Very unlikely that nearby blinks would happen at exactly the same time, even with a 11,000+ multiplier.
