The
comet of 1680 after five or six revolutions
will
fall into the
Sun,
and so much increase the heat of the Sun
that this earth will burn, killing all life.
Since the
Earth appeared
to be built on the ruins of a former world,
such a catastrophe, moreover, had probably happened previously,
which meant that the present inhabitants of our planet had resulted
from a new creation.
