Life currently has a sample size of just one. Without an alien or two to expand the boundaries of biology, Earth’s  evolutionary history set the limits on what we could find  in the cosmos. .

 However,  giants, impossible planets and other impossible planets   and red giants cannot are not the source to find live.  

 But now it seems that a great number of exoplanets will not do, .It seems we are alone in the universe.  

Planets are also need Phosporus  

Phosphorus (P) is one of our planet’s general chemical elements. Without it we would not have RNA , DNA and our ATP, and thus we would not have life.
