well neo, maybe you can answer the questions posed of RL since he is incapable.
RL claimed the oceans were frozen 3 billion years ago. He stated lightning couldn't create life in puddles because there were no puddles when everything was frozen. I pointed out his interpretation of Miller was incorrect. They created lightning in an "atmosphere" and not puddles. His response was to imply there could be no water vapor in the air if the oceans were frozen. I pointed to several ways that water vapor enters the air even in a frozen environment. He responded by only dealing with volcanoes and declaring that water vapor from volcanoes would only be near the volcano. I pointed out this wasn't true. He whined about the air temperature that Miller used in experiments. I pointed out that lightning heats the air several tens of thousand degrees MORE than Miller used.
RLs response was this..
Quote:So did all of these amino acids (formed by lightning) fall from high in the atmosphere into the same square foot of mud, and so have an opportunity to combine themselves , (of their own accord) , into the first self replicating molecule?
Or did they meet thru an amino dating service and have to travel a distance to get acquainted?
It is no wonder that Shapiro thought it beyond the realm of likelihood for first life to be of the 'replicator first' variety. Laughing
So was he implying that Shapiro agreed with him that the oceans were frozen or was he changing the subject because he couldn't respond to the criticisms of his frozen oceans and cold air bluster. RL certainly does NOT say he agrees with Shapiro on any point in his post. He only throws out Shapiro's opinion to attempt to deflect my argument without ever stating if he agrees or not. RL gets all upset when I read things into his statements but when I don't read things in he acts as if I should.
Shapiro postulated a 'metabolism first' start for life because as an award winning chemist, he considered the likelihood of a 'replicator first' start for life to be so remote as to be not worth consideration.
I agree with his assessment of the likelihood of life beginning as 'replicator first'. His favored solution , 'metabolism first' , however I consider as unlikely as well.
Shapiro didn't address the problem of the Faint Young Sun. I didn't state or imply that he did.
However, I raised the issue, and several others as indications of the problems that 'replicator first' scenarios, such as Miller-Urey, must overcome.
Whether you postulate the precursors to a replicator being formed in the atmosphere, on the ground, in the ocean, etc, you have huge obstacles of a practical nature to address.
So if you would like to be specific and say just where you think life began and how, we could have some fun. But I don't expect you to be any more forthcoming than previously, which is to say , not at all.
