This is all best out of theory but my previous astronomy professor introduced the Drake Equation which, through a process of elimination guarantees thousands up to millions of potential alien civilizations in our galaxy. Light-years away despite.
Earth-like planets are a lot more likely than people expect. Every star with its own solar system capable of grasping at least one of these possibilities is quite likely. It really depends on how near or far away they are to the star. Think Goldilocks and the Three Bears, it has to be just right for best results.
