Holy Document Describes Earth

the "great dying" in which some new evidence
suggests that long-time volcanism caused the
massive life loss about 250 million years ago.

asteroids and comets resulting in
devastating global destruction of vast
numbers of living creatures occurring
repeatedly during the hundreds of
millions of years prior to the advent
of any semblance of a creature close
to a modern human?
Holy document describes super-
volcano explosions, many likely caused
by the afore-mentioned asteroid and
comet impacts, with the last one likely
leading to the near extinction of modern
humans circa 74 thousand years ago?
these facts alone, constantly being
refined and expanded upon via the method
of scientific inquiry, place the already
enormous odds against there being anything
remotely resembling the christian god, or
human-centric designer deities, into the
realm of all-but infinitesimally zero, with
the same likelihood of falsity as exist in all
of the fanciful myths of ancient cultures,
mythical fabrications of humans without
a clue about the workings/whys/wherefores
of their natural world?

human evolution suggests that humans came
close to extinction because of a 'volcanic winter'
that occurred 71,000 years ago.
scientists estimate that there may have
been as few as 15,000 humans alive at one time.
