Hey everyone, Brian from Skeptoid here, and we're getting started on our third full-length feature documentary film.

It's called Alien Echoes, a reference to what signs there might be out there in space of another intelligent communicating civilization.

Is their planet showing techno-s techno signatures and biosignatures?

Are they making any outbound communication attempts themselves?

Have a listen to the movie's teaser video.

There is some chance that in the next few decades we will get the signal from some spectacularly distant, spectacularly exotic civilization, and everything on Earth will, as a consequence, change.

We believe that there is probably life everywhere throughout the cosmos.

What kind of life? Is it only microbial? Is it intelligent like us? life everywhere throughout the cosmos.

What kind of life?

Is it only microbial?

Is it intelligent like us than building radio telescopes and spacecraft?

There may be highly evolved civilizations and cultures out there with art and history and science,

but underwater, under tens of kilometers of ice, on worlds like our own

Europa or Titan, and they may have no concept of the universe.

Whatever that life might be, the one thing we know about them for sure is that they're not

in touch with us, and we don't see any evidence that they ever have been.

Frank Drake's famous equation estimated the number of communicating alien civilizations

by comparing the number of stars against all the improbabilities, stars having habitable planets,

planets developing life, life becoming intelligent,

and so on.

But for some of these variables, we just don't know. We have no idea how many communicating

civilizations might be out there. Five or five million.
