Courage, maybe. But intelligence?
If a wandering mass as large as the Moon decided to wander
by Jupiter, be flung at Mars, which then flings it here,
and back to Mars (or was it Venus?), the expressed momentum
deltas would not be all that conducive to current circular
orbits, nor would the duration of said flinging last more
than maybe a decade (since that's about the free travel
time of a body at 42 m/s -- Sun-orbit escape velocity at
1 UA -- shuttling between Jupiter, Mars, and Earth).
If the moon were to -- somehow -- suddenly develop a mighty
rocket propulsion engine (say, maybe, a few billion tons
of radioactive waste, and even then that might not be
enough -- oh, hi Barbara Bain! :-) ) to suddenly propel
it *towards*, then *past* Earth, eventually escaping out
of the Solar System, then the Earth would rebound.
How much? Well, lessee. The Moon has 7.35*10^22 kg.
The Earth, 5.976 * 10^24 kg. The Earth currently meanders
around the Sun at just under 30 km/s. Escape velocity
is therefore ~ 42 km/s -- a *minimum* delta of 12 km/s or a
momentum shift of about 8.82*10^26 kg-m/s. That requires
the Earth, in order to counterbalance the momentum, to
change its velocity by 148 m/s in the other direction.
That's a change of almost 0.5%.
I'm not sure how that delta would express itself, but it
would definitely change the Earth's orbital period,
probably by about 2.9% if I understand the cube-square
orbital rule correctly.
2.9% of 365 = 10.5 days, which by a coincidence is about
the number of days sliced out of 1752 (Sept 3 through 13
are basically gone) by Pope Gregory IX. However, the
Pope didn't correct every year, just that particular one.
Color me skeptical.

Let me put it to you this way.
Velikovsky wrote a book. By itself, it's about as much
evidence as my works are illustrative of inter-universal
travel. (I should also note that my ideas aren't all that
original; they're loosely based on Roger Zelazny's _Amber_
series. :-) But he didn't mention the Chinese lanterns.)
Now, had you or Immanuel Velikovsky bothered to
produce real *artifacts* -- I'm not sure what would be
illustrative, but such things as stress fractures and
such at the correct time intervals on all three of Mars,
the Moon, and Earth might be acceptable, and only if the
computations show that The Wandering Rock is even possible
with the current orbits -- there might be something to
all this.
AFAIK, all he had was rather vague statements in a certain book
revered by a minority of Earth's population (I'd suggest gently
that more people read the Qu'ran than the Bible).
Believe what you like, but I believe this is more or less
useless nonsense. However, it does make for an interesting
problem in astronomical physics, so I've forwarded it
appropriately. :-)
