What do you think of this idea?

 It could easily be possible that we are the most advanced civilization. I
once read an book by Dr. Issac Asimov which postulated that the moon is the
primary cause of evolution on this planet. We live on a planet that can be
described as a double planet due to the relative size of the moon. The moon
has an enormous influence on the tides. These tides have thrown sealife at
the beaches for eons and probably speeding evolution up quite dramatically.
The sun also affects the tides but to a much smaller amount.
  Our civilization could reach out to the stars one day only to find planets
containing single celled creatures, unless we find another double planet
system.
  If anyone is interested the book was called "The tragedy of the moon"

Interesting idea. But don't you think life would have found a way to
evolve even without tides?
