Lets be generous. Depending on how 'raw' you are defining as 'raw chemicals' , one could say that ALL ingredients were here.
Ok, we agree.
real life wrote:rosborne979 wrote:* We know that the conditions were very energetic (good for chemical reactions) and very varied.
As they are today. Lots of variety, constant changes
Ok, we agree.
real life wrote:Which means also that chemical reactions can go both ways; and the likelihood of the type of molecule you need surviving in the open (whether in the mud or in the ocean or wherever) is nil.
Just because chemical reactions go both ways doesn't mean that the possibility of some replicative molecule surviving is nil.
real life wrote:rosborne979 wrote:* We know that at some point, simple DNA based life existed.
Yes of course.
We agree.
real life wrote:rosborne979 wrote:* We know that DNA and RNA are too complex to have resulted from a non-replicative precursor.
Yes. Not good for your side.
Perfectly fine for my side since we always assumed DNA/RNA had precursors. So we agree on the basic fact I stated anyway.
real life wrote:rosborne979 wrote:* We know that Poofism is ruled out because we're doing science (not mythology)
That doesn't mean that the supernatural is impossible, ros. It means that science has limits. Accept it.
I do accept it, that's why poofism is ruled out. So we agree on this one as well.
real life wrote:rosborne979 wrote:* Therefor, some replicative molecule (probably many generations of them) must have formed after the raw chemical stage, and before DNA/RNA.
And you have NO evidence of these 'many generations'. NONE.
I notice you only complained about the "many generations", not the basic deduction. So I guess we agree again.
real life wrote:rosborne979 wrote:Do you have a different deduction to make from those facts?
Take note that some of these 'facts' are not facts at all. They are rosy assumptions.
The only assumptions made in that sequence came from you, and were inaccurate and unsupported. You agreed with the actual facts I provided, right down the line. Now you are claiming there were assumptions in that list. Which of the items
I provided do you not agree with?

He is proposing how to get to a living organism without a replicative molecule because postulating an 'independent replicator' that leads to first life is a waste of time, and he's not wasting his thinking about it.
More accurately, he is proposing how to get
thermodynamic life (not necessarily an
organism) without a replicative molecule because he believes that an independent replicator can not arise spontaneously without a transitional element (which he is proposing).
So Shapiro is proposing a transitional mechanism between raw chemicals and a replicator. Exactly what I said.
