The puncuation fits this phrase

The Earth is the only world known so far to harbour life.
There is nowhere else, at least in the near future,
to which our species could migrate.

and this phrase.

Our planet is a lonely speck in the great enveloping cosmic dark.
In our obscurity,
in all this vastness,
there is no hint that help will come from elsewhere to save us
from ourselves.

But the last letters do not seem to match in Either phrase. Interesting.
