    Actually, I mean plausible as seems likely to me. Of course, that does not
    carry significantly more weight.

    The problem of generating IC or SPI will seem more serious to non-ID folks
    if it can be shown that they exist in nature. Neither the definition nor
    the detection of these is adequately clarified to be very useful. There
    has been progress in developing evolutionary models for the origin of
    several complex biochemical systems, despite our rather rudimentary
    knowledge of their working and the nearly nonexistent fossil record of
    biochemical systems. This suggests that drawing a line and declaring that
    scientific discovery will not pass it is unwise. Saying that you do or do
    not think it will happen is certainly reasonable; that it cannot is the
    error.

    I was uncertain whether you meant nature achieving things on its own as
    physically or theologically descriptive. The existence of nature, much
    less anything happening, depends on God maintaining it. Depending on your
    Calvinist or Armenian leanings, you may think of God as causing or allowing
    events, but they are not independent of Him. It is important to maintain
    the distinction between creation and the Creator, as you note. Nature is
    the proximal cause for most events, but God is the ultimate cause. "God,
    in His ordinary providence, maketh use of means, but is free..."
    (Westminster Confession of Faith).
    Deism asserts that god is not currently involved in things, having wound
    nature up and left. This is also the implication of Johnson's claims that
    macroevolution disproves God, except that Johnson has him coming back to
    rewind frequently.
