Some years ago there were three competing theories about the moon's
origination. 1. The moon was the result of a coalition of the debris
that once circled around the primal earth. 2. The moon was a captured
asteroid. 3. The moon is the result of an asteroid that crashed into
the earth and bounced into lunar orbit. Analysis of the moon's surface
confirmed the third theory. Now a massive asteroid that crashes into
our earth and bounces into orbit doesn't recede into space immediately
after the impact at the rate of 4 cm per year. Think about it.

Hi Lee,
Jon's link to talkorigins is a great place for debunking YEC arguments.

Here is the AIG claim, I would assume....
The moon is slowly receding from earth at about 1-1/2 inches (4cm) per
year, and the rate would have been greater in the past. But even if the
moon had started receding from being in contact with the earth, it would
have taken only 1.37 billion years to reach its present distance. This
gives a maximum possible age of the moon-not the actual age. This is far
too young for evolution (and much younger than the radiometric 'dates'
assigned to moon rocks).
Since the Moon-Earth distance is 3.85 x 10^10 cm, and the rate of
migration is ~3.8 cm/yr., this suggests the Moon is on the order of 10
billion years of age.
Of course, the unknown history of the Moon's orbital eccentricity and
Earth's continental distribution, along with other variables, prevent an
accurate assessment of the history of the Moon's orbital migration.
For a little more detail, the migration rate is proportional to the
tidal stress, and the tidal stress varies as the inverse cube. So, for
instance, when the Moon was 5 times closer to the Earth, it would have
received 625 times the tidal stress that it does today. This would have
slowed the Earth at a much quicker rate, and, consequently, increased
the migration rate of the Moon accordingly, as expressed in the
conservation law of angular momentum.
