The entire universe is fine tuned for life as we know it. It's so improbable that science can't explain it based on chance alone and so have had to come up with the idea of an infinite number of multiverses to justify the existence of the uniqueness of our universe.
A) How could we possibly know that given so many unanswered questions about life in just our own solar system & the fact we have not (yet) ventured beyond our own solar system in a quest for life?
B) "Life was we know it" may be just one in numerous forms of life. Given billions of galaxies & trillions of stars, my guess is we have an extremely small notion of what exactly life is and how it exists throughout the Universe.
The quest for other life or additional life is barely in its infancy.
