From my point of view, I'm quite happy to say that life does not exist anywhere else in the universe and as I suggested before, life on earth is merely a transitory accident that will cease comparatively soon in the grand scale of things.
Humans will never contact any non-terrestrial entity, 'cos there ain't none! Migration to other worlds is just a schoolboy imagining that can never occur. Eventually, long after humanity has disappeared, the sun will go supernova and engulf the earth, which will then become an insignificant cinder! (as opposed to the insignificant blob of mud, water and rock that it is now)
It is impossible for anything digital to sound analogue, because it isn't analogue!
