    I am not defending "coercive" or "irruptive" divine "interventions" in
    Howard Van Till's sense of the terms. I prefer to believe in acts of
    divine _providence_ infusing novel information at many points. At the
    scientific level, they would not be detectable, being at the level of
    quantum uncertainties or "random" events.

    But can you specify any feasible scientific tests for the following
    propositions? (If not, why not?)

    (1) Life can emerge spontaneously by purely natural means.

    (2) Novel enzymatic activities (not slight modifications or new
    combinations of pre-existing ones) can emerge spontaneously by purely
    natural means.
