Where are the Extraterrestrial Civilizations?

Reference the Drake equation and the Fermi paradox.

There have to be those among you who “believe”.  And I’m not talking about faith that Hillary Clinton is a lizard with a human skin. That’s only speculation at this point.

About 50 years of the Search for Extraterrestrial Intelligence (SETI) have failed to find anything, even though radio telescopes, receiver techniques, and computational abilities have improved enormously since the early 1960s. All we have discovered is that our galaxy is not teeming with very powerful alien transmitters continuously broadcasting near the 21 cm hydrogen frequency. 
Maybe the answers are at Area 51, but I doubt it.

  1. As a species, we arrogantly assume our little blue marble, and it's life forms, interest extraterrestrials. Or, they observe examples like Shillary and go, "Ugh, gross", and move on.

  2. There are numerous theories about why nothing's been picked up. We could be living in a part of the galaxy where everyone in other solar systems aren't as advanced as we are and the really advanced civilizations are elsewhere, or perhaps we're just listening to the wrong frequency. I think perhaps aliens have picked up TV broadcasts of old movies and mistaken them for documentaries. Earth has never lost an interplanetary war. They fear us.

  3. There is also the possibility, however remote, that we are indeed alone. There is also the possibility that interstellar travel is, for whatever reason, impossible. We don't know what we don't know.

  4. That unfortunate creature in the graphic looks like what you'd get if you crossed John Kerry with Robert Francis O'Rourke then bred the results for a hundred generations without outcrosses. It's probably Progressive (and hypocritical) as well, only without the wit to marry an heiress….

    As to extraterrestrial life, my crackpot theory is that any civilization that advances to industrialization either nukes itself back to the stone age, or drowns from global warming. So there.

  5. " Adaptation is a consequence of
    evolution, and since evolution is the only reasonable
    explanation for complex life regardless of substrate,
    adaptation should be inherent to it. "
    There's a wrong assumption.
