: Not true. The accounts I've seen, gleaned from simulations, suggest

Too bad the icy proto-moon itself couldn't have merely glanced off of
Earth, and of not so long ago.

It's a matter of regular old physics, whereas such lithobraking
encounters simply were not all that uncomon. (could even happen once
again)

At some time near or shortly after the bulk or worse portion of that
last ice age cycle, of which this planet will ever see, is when Earth
got a good seasonal tilt worth of an impact, receiving a few spare
thousand teratonnes worth of salty ice, having created another nifty
ocean basin and the antipode, plus ever since we've been summarily
thawing out, along with as much global dimming via humanly contributed
soot and chemical polution as we can muster.

A shift from a thermal energy sink worth of a highly reflective ice
age, into going GW postal takes a truly great deal of applied energy
over an extended period of time, some of which unavoidably becomes our
demise via our self imposed global dimming and a few other facters
that should never have transpirored to the extent we've allowed.
However, the vast bulk of energy is off-world via gravity and tidal
forces (applied inside and out) that arrived along with our more than
somewhat salty and originally icy proto-moon.

At least there's nothing within the regular laws of physics, or that
of any known planetology which excludes such a recent event, and
there's yet no clear objective evidence proving we even had that moon
establish within it's relatively final orbit as of prior to 10,000 BC,
if not somewhat more recently.

For example, if that moon had ever been orbiting for any amount of
time while being situated at half or that of much less distance, as
such the applied tidal forces of at least four times the intensity
(inside and out) would have been downright lethal trauma imposed upon
most any significant form of existing life upon this newish planet
that had gained more than it's fair share of salty oceans and of many
other bodies of salty waters.

All of the arguments opposed to this recent merger and orbital trek of
our unusually massive and nearby moon are yet every bit as subjective,
and otherwise extensively faith-based upon all such horrific things
happing to our world in the very beginning of planetology formations,
that which supposedly had nothing whatsoever to do with any other star
or exo-solar system but that of our own.  I guess that means the
Sirius star/solar system is Muslim, while our's is becoming a whole
lot more Jewish mindset by the day.

Damn few of us, including the honest likes of "Jean-Paul Turcaud", are
simply not sufficient to alter the ongoing self-destruct mode of
what's insuring a good part of our very own demise, that's also
getting more spendy and otherwise lethal by the day.  Too bad we still
haven't established zilch worth of any Earth/moon science as could
have been easily and efficiently obtained from the superior
perspective of having our instruments situated within the moon's (M--
>L1---->E) sweet-spot, as of decades ago.
