Good luck. We're real slow.

   <shaking head> Scientific evidence? None!

What do you have against our planet
being just one of many containing
human beings, Sam?

  I have no problem embracing the possibility of live all over
  the cosmos including other places in the solar system, and
  look forward of EVIDENCE of live in other places.

  The probability that other life had identical DNA as humans
  is just about ZERO.

  Evolutionary processed in different places produce different
  life forms and species. Humans would not have survive on our
  planet in many earlier epochs.

  Relativity petty much prohibits advance technical civilization
  (assuming such exist) from any reasonably fast travel even between
  stars. Alien spacecraft, the probability, thereof, is just about
  ZERO.

  John, you have a tough time sorting science from science fiction
  and speculation.

  I'll bet that the cosmos is teaming with life... but it doesn't
  visit here on spaceships.  Perhaps microbial life on a meteor,
  but not what you fantasize about. John.

If you find a blueberry bush in
a field do you say, "OMG!! This could
only happen once? Or do you
expect to find more blueberries?

I would think it comforting.
