10 billion galaxies in the universe,
an average of 100 billion stars in each one of those.
That’s 1 billion trillion (that’s a one and 21 zeroes) of stars in the known universe.
At least  10 percent of those may have at least 1 planet;
that is 100 trillion (that’s a hundred and 18 zeroes) of planets.
There might (“might”) be about 11 billion planets similar to ours,
of those, we concretely know of about 10 (ten. One one, one zero),
that number includes us,
and we only know there’s life in one of those 10,
us;
that is a percentage of 0.000, 000, 000, 000, 000, 001
of 100 trillion.

Well, ****.
