Murchison Meteor Questions

It can be disproven. You just have to prove, first, that there's absolutely no life on Planet Earth.The problem you and Lewontin both seem to have is the fact that you can't seem to tell the difference between theories that can't be disproved because they're unfalsifiable and therefore bad science; and the theories that can't be disproved because they're not wrong.You can't disprove a correct theory, except with evidence that doesn't exist. Lewontin's objection to the fact that evolution and abiogenesis can't be disproved with the current evidence is meaningless. If abiogenesis and evolution were wrong, there would be abundant evidence that this was so. That's a considerable difference from an unfalsifiable theory like those proposed by creationists, which can't be disproven by any conceivable, hypothetical evidence.

I can't have evidence for what is a contradiction in terms. There can't be any such thing as a "pre-biotic organism", because any organism by definition must be biotic.If you want to know about the prebiotic chemical precursors of the first organisms, I plead ignorance, and can only attempt to direct you to the scientific consensus on the issue. That kind of biochemistry is something that I know little about, as yet.It was soley my intent to speak to your misunderstanding about what "falsifiable" actually means. Did you have a comment in response to my remarks on that subject?Edited by crashfrog, : No reason given.

I don't see it that way at all. We're looking for the chemical precursors to life. There's nothing contradictory about that. At some point, an increasingly complex chemical system became complex enough to be considered "life", but that's a fuzzy boundary, like "when does it start raining?" (It's not raining when a single drop of water falls on you, nor when two... fifty in two minutes is probably a good rainstorm, but where exactly in between fifty and two does it start raining? It's a gradient, not a sharp boundary. So too with life. There are some chemical systems that are so simple we don't consider them alive, and some chemical systems that we definitely consider alive, like a bacterial cell; but where in between not-life becomes life is a fuzzy boundary.)It contradicts your Bible, sure; but so what? Have what backwards? I have literally no idea what you're trying to say, here.
