There's likely no other life within the observable universe. There are only about 10 billion galaxies, each galaxy has less than 100 billion stars that have a habitable zone, and not all of them planets that could support life. If we're being generous, that leaves only like 10^15 solar systems in the observable universe that have planets that could support life. The chance of life coming into existence on one of those planets is well less than septillianth of a percent, so it's highly unlikely for there to be life elsewhere in the observable universe.
