ok... excellent. So by most timelines including yours... life had to evolve from non life in a far shorter time than it took unicellular life to become multicelluar. About a billion years... some of which earth spent as molten magma.
Yes, but the reason for that is that the earth, especially the seas, needed to be chemically transformed by those early photosynthetic organisms. Oxygen levels needed to come up, among other things before higher organisms could thrive. Hard rock needs a lot of time before a forest can grow on it. But science is still pretty ignorant of how those first molecules came to be and became self replicating and then became cells. There are theories but we simply don't know enough yet to say with any assuredness. No argument from me there. But that is different than saying it could not or did not happen via natural processes or that randomness did not have an important place in the process.
I simply quoted top minds in science saying it is highly unlikely it happened by chance... I did not say it could not or did not. Basically we agree about the state of science but I probably emphasize the "highly unlikely".
Highly unlikely is a good one, other scientific phrases I like are "sorta probably", or "woulda shoulda" and also "tini bit".
how about not plausible.... or highly improbable... or almost a miracle. Some of these quotes are from the biggest names in the field including nobel prize winners. Like I said I present science and scientists. Most of the hate religions types are stuck in a 1950s worldview. Reality is... that evolution and or creatiion by random chance is all but a dead idea and it is far from the science we see today. Does that mean I am arguing science says Jesus or God did it... no... that is b.s. floated out there by Free Thinker or Stu... when I use science to them to be stuck in 1950s ideas. Quote from jem: -- http://web.mit.edu/rog/www/papers/does_origins.pdf We now know that the probability of life arising by chance is far too low to be plausible, hence there must be some deeper explanation that we are yet to discover, given which the origin of life is atleastreasonably likely. Perhaps we have little idea yet what form this explanation will takeâalthough of course it will not appeal to the work of a rational agent; this is would be a desperate last resort, if an option at allâbut we have every reason to look for such an explanation, for we have every reason to think there is one. In a detailed survey of the field, Iris Fry (1995, 2000) argues that although the disagreements among origin of life theorists run very deep, relating to the most basic features of the models they propose, the view sketched above is a fundamental unifying assumption (one which Fry strongly endorses). Some researchers in the field are even more optimistic of course. They believe that they have already found the explanation, or at least have a good head start on it. But their commitment to the thesis above is epistemically more basic, in the sense that it motivated their research in the first place and even if their theories were shown to be false, they would retain this basic assumption. 3 There is a very small group of detractors, whom Fry (1995) calls the âAlmosta Miracle Campâ including Francis Crick (1981), ErnstMayr (1982), and Jaques Monod (1974), who appear to be content with the idea that life arose by chance even if the probability of this happening is extremely low. 4 According to Crick âthe origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to been satisfied to get it goingâ (1981: 88); the emergence of life was nevertheless a âhappy accidentâ (p. 14). 5 According to Mayr, âa full realization of the near impossibility of an origin of life brings home the point of how improbable this event was.â (1982: 45). Monod famously claimed that although the probability of life arising by chance was âvirtually zero. . .our number came up in the Monte Carlo gameâ (1974: 137). Life, as Monod puts it, is âchance caught on a wingâ (p. 78). That is, although natural selection took over early to produce the diversity of life, its origin was nothing but an incredibly improbable fluke.Does Origins of Life Research Rest on a Mistake? 459 However, the vast majority of experts in the field clearly define their work in opposition to this view. The more common attitude is summed up neatly by J. D. Bernal. [T]he question, could life have originated by a chance occurrence of atoms, clearly leads to a negative answer. This answer, combined with the knowledge that life is actually here, leads to the conclusion that some sequences other than chance occurrences must have led to the appearances of life. (quoted in Fry 2000: 153) Having calculated the staggering improbability of lifeâs emergence by chance, Manfred Eigen (1992) concludes, The genes found today cannot have arisen randomly, as it were by the throw of a dice. There must exist a process of optimization that works toward functional efficiency. Even if there are several routes to optimal efficiency, mere trial and error cannotbe one of them. (p. 11) It is from this conclusion that Eigen motivates his search for a physical principle that does not leave the emergence of life up to blind chance, hence making itreproducible in principle: The physical principle that we are looking for should be in a position to explain the complexity typical of the phenomena of life at the level of molecular structures and syntheses. It should show how such complex molecular arrangements are able to form reproducibly in Nature. (p. 11) According to Christian de Duve (1991), . . .unless one adopts a creationist view,. . .life arose through the succession of an enormous number of small steps, almost each of which, given the condition at the time had a very high probability of happening. . .the alternative amounts to a miracle. . .were [the emergence of life] not an obligatory manifestation of the combinatorial properties of matter, it could not possibly have arisen naturally. (p. 217) Not all theorists follow De Duve so far as suggesting that lifeâs emergence mustbe inevitable. While nota specialistin the area, Richard Dawkins (1987) captures the attitude that appears to dominate scientific research into lifeâs origin. According to Dawkins, All who have given thought to the matter agree that an apparatus as complex as the human eye could not possibly come into existence through [a single chance event]. Unfortunately the same seems to be true of at least parts of the apparatus of cellular machinery whereby DNA replicates itself (p. 140)460 NOUS Ë In considering how the first self-replicating machinery arose, Dawkins asks âWhatis the largestsingle eventof sheer naked coincidence, sheer unadulterated miraculous luck, that we are allowed to get away with in our theories, and still say that we have a satisfactory explanation of life?â (p. 141) And he answers that there are strict limits on the âration of luckâ that we are allowed to postulate in our theories. 6 According to Dawkins, an examination of the immense complexity of the most basic mechanisms required for DNA replication is sufficient to see that any theory which makes its existence a highly improbable fluke is unbelievable, quite apart from what alternative explanations are on the table http://web.mit.edu/rog/www/papers/does_origins.pdf
You're saying life from non life didn't or is highly unlikely to happen by chance. So chemical reaction and environment make it not by chance - but inevitable - then. Where's your problem exactly?
If you studied this recently or even gave a thought to what those scientists have written in the MIT survey paper I cite... you would understand that if chemical reaction and environment really does work together to make life inevitable, in the next thought you have to ask who or what set up the universe for life arise out of the chemicals. And you already know that most top cosmologists say the universe does appear incredibly fine tuned for life. you need to understand why these famous scientists are willing to tell you that it was so unlikely for life to arise by random chance... http://web.mit.edu/rog/www/papers/does_origins.pdf We now know that the probability of life arising by chance is far too low to be plausible, hence there must be some deeper explanation that we are yet to discover, given which the origin of life is atleastreasonably likely.

The universe is clearly not set up for life. If it were set up at all, then it was set up to be empty. Most of it is empty space lethal to life. Chemical reaction and environmental circumstances set up conditions for life to arise, not the universe. As for your 'who' question, 'something else' or a God set up is really not at all necessary or even sensible .
