Actually EP, it was a "comet" that Velikovsky proposed
destroyed the parent body to form the asteroid belt
and devastated Mars (produced the Chasms), reversed
Earths poles, and eventually became Venus. I thought
Harry was just good-naturedly ribbing you for
"borrowing" from Velikovsky and trying to sneak it
past us.

You've always given me the impression of being a very
well-read person, particularly of esoteric and
not-popularly-held topics. Apparently, the stigma
attached to the Velikovsky name still runs strong in
some archeological circles.
