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.
