	Biologists have had another explanation for a number of years.
It is known that clay-surface-layer catalysis is capable of generating
polarized organic compounds.  Considering that clay particles would
have been present almost as long as the Earth, I think this is quite
adequate as an explanation.
	The basic fallacy of this creationists' approach is the implicit
assumption that an incomplete explanation is inadequate, and that unknown
*details* invalidate the entire concept.  If this were so *all* scientifiec
theories would be invalid, since *none* is complete, and all include
"I don't know"s.
