What I find kind of amusing about all this is that the whole premise of why we're looking at these stars (that changes in the star's light indicates a planet is passing between it and us) is based essentially on a guess. Sure it makes sense and thru it we can explain some of the questions we have about the universe but until we verify it thru direct observation it's still just a guess. It's like the people back in the days of Columbus, when they believed the world to be flat, trying to explain the why's and how's of ocean currents.
As for intelligent life in the universe? Well there might be and there might not be. One thing is sure though, the universe is so big and the number of galaxies so vast that it is mathematically against the odds for there not to be. When it comes to the possibility of intelligent alien life somewhere in the universe, to paraphrase Frank Sinatra, if it can happen here , it can happen any where.
To me, the real issue regarding potential alien life is the distance between things in space. If we ever did find a planet that we were certain that could support us it would be near or completely impossible to get there. So why waste time trying to find life in the universe as they too are likely limited by distance. If by some chance though they did have the ability to achieve intergalactic space travel they would be so advanced that there would be nothing of interest for them to want to come here because there is likely something more convenient with equal or greater amounts of whatever they might have wanted to come here for. Think of it like this, if you're in an office building in an office 100 stories above ground in a city full of skyscrapers and you become mad and feel an urge to punch a wall, are you going to run down 100 flights of steps, catch a cab to the other side of the city and then run up 100 flights of steps and punch a wall there or are you going to just walk a few feet to the nearest wall in the first office and punch it?
