No analogy was made to mountains on Earth resting on sand other than to
point out that sand and other loose soils can indeed support structures as
large as major mountains, which is true. As to the idea that mountains are
rooted in sand - your imagination and sense of humor were running full tilt
while your brain was lagging slightly.
