    You want to go back to earlier posts? OK, here goes.

    "could not or would not..."? I make no argument re "could not or would not."
    That's putting words into my mouth. I am simply stating my own
    presuppositions as plainly as I can, without giving a long explanation re
    reasons for choosing those presuppositions.

    In the context of this thread, OK. I don't recall claiming any more than
    that.

    Of course not. But in choosing presuppositions, logical consistency is not
    the only or primary consideration. It would be just as logically consistent
    to replace #2 with the proposition, "Each biblical 'kind' was independently
    created by God." However, I think we would agree that such a proposition
    deserves evaluation on the basis of other than purely logical
    considerations.

    Let's look at your statement #1 again.

    >> 1) The Universe had to be fine-tuned for life-supporting chemistry, stars,
    >> etc.

    "Had to be"? What evidence is there for the necessity of fine-tuning? If you
    want to be precise, there is only evidence that the fine-tuning hypothesis
    provides a satisfying scientific explanation for the properties and
    parameter values observed. One could, with the logical consistency that you
    proclaim so valuable, propose that God simply gave being to a 'mature'
    universe having this appearance. Similarly, one could, with logical
    consistency, propose that God simply gave being to a set of species that
    only appear to be genealogically related. Dependence on logical consistency
    alone will get you nowhere.

    > In fact, our current state of knowledge
    > supports both #1 (fine-tuning has been observed) and #2 (biogenesis has
    > never been observed).

    But, of course, your #2 appeals only to a lack of evidence. You could craft
    a book full of loony hypotheses and declare that none of them were
    contradicted by #2. Not a big victory there for ID.
