Well I'm not saying it was: the point is that the theory of evolution can and should be logically separated from hypotheses about abiogenesis.
You have to remember this is supposed to be a guide for dummies - which why I do the writing and get all the praise while you do the technical work and don't get any!
Now, I quite accept what you're saying, but I'd rather present the entirety of evolution, from a cloud of gas to humans, as one simple concept. It's obviously enormously complex, but if it's reduced to a series of very tiny steps, I think a lot of the issues go away.
The more I think about it, the less importance I see abiogenesis has.
What about these:
When the earth become the earth? As in, at which specific point in time did it change from being a cloud of gas to being a planet? When it was at a specific density? When it had taken shape?
When did a human become a human? What species was the first human's mother?
Those questions are irrelevant, as far as I can tell, so why should we attach any particular importance to abioegesis?
As you say, it means "life from non-life", but all that means is that at one specific point in time, the ________ (whatever it was) becomes classed as "alive", The previous molecule/thing, which is 99.9999999% the same as the "live" one is itself, not live. If there's no special relevance attached to this singular event, it loses its importance. I'm pretty sure this is where tracer was coming from with this bit:
tracer said:You must must must make it absolutely clear that the theories on how the first self-replicating life arose are completely separate and distinct from the theories on how evolution has progressed since then.
We do see abiogenesis as more of a leap than a step. Imagine a staircase with a million stairs. Isn't abiogenesis just one of the steps, with no more importance to us or The TruthTM than the specific instant the earth became a planet? For scientists, obviously, its a fairly important part of it, but to a layman, I don't think it's that necessary.
While this is a thread entitled Evolution: the Facts, it sure as hell isn't going to cover all of the facts. As you say, we know that biopoiesis happens and I think that might be enough. Do we have to pinpoint one specific example at one specific time which becomes classed as "alive"?
I'd go for:
Atoms > molecules > more complex molecules > even more complex compounds, one of which happens to be alive > even more complex compounds, one of which happens to be human.
Do you think it's reasonable to take that approach?
(Albeit with a few more steps, maybe?)
