Even if there were only one living organism in this massive galaxy

There are infinite living beings in this entire universe.
Sometimes they might be single-celled,
sometimes perhaps just plants.
Sometimes they might be intelligent life forms. We don't know,
but looking at the ratio of planets within a galaxy,
water is more than common; it is close to an essential component.
And we will probably discover at least microorganisms
before we die.
Just looking at Europa, for instance.
Or, even if there is no direct evidence yet, there is circumstantial evidence
on Mars as well.
In other words, what does this mean?
This universe is an infinite space where life breathes.
