Recent study challenges a widely held anti-ET argument based on evolution
Intelligent life beyond Earth might not be as dim a hope as many scientists think, according to a new study challenging a widely held anti-ET argument.
Many skeptics tout an idea called the anthropic argument that claims extraterrestrial intelligence must be very rare because the time it takes for intelligent life to evolve is, on the average, much longer than the portion of a star's existence that is conducive to such life.

I honestly feel that most scientists haven't taken that theory seriously in the first place. I'm not sure how long a star's existence could be "conducive to life," as the article says, but I have no doubt that it's hundreds of millions or even billions of years. Take a thousand years - now take a thousand of those - - - now take THAT a thousand times over - - - then double it or even triple it. That's a
long time.
