Well, so far the response has been that abiogenesis (spontaneous
generation) is OK as long as the form that appears is undifferentiated.
Maggots or even bacteria cannot spontaneously appear; they are too
complex.  So that leaves us with: what is undifferentiated life?  Is an
autocatalytic set sufficiently generalized and undifferentiated?  Is it
alive?	Or is some measure of compartmentalization required to define a
discrete entity?  That would probably constitute a differentiation, though.
Perhaps the entire primordial ocean (or maybe just the ocean bottom)
could be considered alive, with the entity's boundaries being supplied by
pre-existing structures.  No DNA, no RNA, no genetic material at all,
just a lot of metabolism in a big chemical reactor.  Is it alive?
Has abiogenesis occurred?
