There were perhaps
one hundred billion galaxies in the universe,
and each galaxy contained a hundred billion stars.
How many of those stars had planets,
and how many planets had life?
(...)
The belief
that there was life only on this pale blue dot,
in this insignificant solar system, now seemed
as absurd as the ancients' naive belief that
the sun and the stars revolved around the earth.
