@Leadfoot,
he made it clear, you did not. You cannot escape the baggage of your past posts. His view is one scientists printed op ed. Its neither a groundswelling or an endorsement of anything.
I dont think hes saying what you wish though.
He is saying that (with todays level of knowledge) he does not feel that we YET fully understand the entire chain of events that resulted in life. HE feels we aint even close. Well, there are other "experts" who disagree with that op-ed position. So what, research will keep going on, we are NOT gonna quit because some Wag has capitulated .
I can also accuse him of shortsightedness in that he seems to feel that today's living state is exactly the same as it was at its inception.
He has no evidence of that either.
Several of the abiogensis ideas(nd these are closer to theories than some others), state that life, at its inception was a polymer bag of specific isoprene chemicals that changed the environment by routine (By todays environments) chemical reactions, NO RNA, NO DNA etc etc. Chemical paleontology from more and more Hadean sites discovered around the world, seem to agree with each other(NONE of these sites refute the concept)
