Although we don't know for sure either way, saying that it's unlikely for
an
alien species to be 1 billion years ahead of us because, "...it took
intelligent life on this planet around 14 billion years to get where it is
today..." is incorrect in principle. It took us 14 billion years to "get
where we are today" because our sun didn't even FORM until 4.5 billion
years
ago. In effect, it only took us 4.5 billion years, give or take. Since
stars have been forming constantly for the past 12-15 billion years
(depending on whom you ask), if an intelligent alien race popped up around
a
star that formed a MERE 6 billion years ago, they could very well be 1
billion years ahead of us technologically and culturally (and several
billion years farther along than that if you concede that their star
formed
perhaps 9 or 10 billion years ago).
The point is, there has been PLENTY of time for SEVERAL intelligent
species
to develop, each one a billion-or-so years more advanced than the previous
one.
