We are all Carbon Based Units, from the Universe. So the Universe is discovering itself?......I'll answer that. Yes.
So when did the first radio wave/signal leave earth, late 1800 early 1900's? So what's that, 120-130 years ago? How fast does a radio signal travel?... The speed of light? What's that, 1,860,000 miles per. second? So that first signal is only 130 light years from earth, which is nothing in the big scheme of things.
I guess my point is, if there's other intelligent life out there; no one will know we're here for a very very very long time. But it's fun to think about.
