The Drake equation is Quack science.,(reply>), Kind of missing the point. The equation isn't 'quack,' it just does not provide any answers. As Lex demonstrates in this video, it is a structure to provide answers thru science, eventually, or speculation, today.,(reply>), Only astronomers and astrophysicists believe the Drake equation and in SETI. I'm a retired biologist and don't believe for a moment that any life could live on the cold outer moons.,(reply>), @Velocity Labs WOOSH!,(reply>), Exactly, it's not even science.   Like Michael Crichton explained "The Drake equation can have any value from “billions and billions” to zero.  An expression that can mean anything means nothing. Speaking precisely, the Drake equation is literally meaningless, and has nothing to do with science."
