Almost zero I would guess. There may be life that is millions or billions of years ahead of us. Or behind us. Even just a few years off of where we are changes a lot of things.
Edwin Hubble only theorized
80 years ago that those little "smudges" everybody saw mixed in with the stars are other galaxies separate from our own and not nebulae
within our galaxy. In other words prior to that theory, which is now a proven fact, people did not realize that the universe goes way past the Milky Way. So almost overnight, the size of the universe went from
100,000 light years to the current visible universe of over
50 billion light years
We are still in an infant state of our comprehension of what lies out there.
Cool videos to show size in the universe complete with groovy music:
