we are finding out know that intelligent life maybe even harder to come by then originally thought. The drake equation is a bit out dated and a new equation is more up to date with what we now know.

Plate tectonics is thought to be a necessary need for a habital planet...so is a massive giant like Jupiter to occupy the many asteroids and comets with their hefty gravitational fields. Theirs other new thoughts in the paradigm...but those are a few. Still...i'm thinking millions of possible habital planets in our galaxy alone.

still far under what drake proposed
