Many.
Now take all the years those planets existed.
Many.
Now take all the molecules on all of those planets.
Many.
In order to have life all you need is 1 self replicating molecule.
Whats the chance of life appearing somewhere at some point? Big.
Of course life exists on billions of planets in the universe. The problem is that we will never see any of it, except for some nasty bacteria and viruses we might pick up in our own solar system. What is fairly certain is that our particular life forms are are unique to Earth. Intelligent life on other planets will be very different from us because their planets will be different, with different gravities and atmosphere compositions. Plus their bacteria and viruses will have affected their physical appearances and maybe even their psyches. IOWs, they won't look like us and may not even think like us.
