Sorry this took so long but here it is. You are in brown.
How has science dispelled the possibility of spontaneous generation? There are many papers which say that we don't understand how it happened, but that is a different thing entirely from saying that it couldn't happen.
I would say my strongest argument for this is the probability that a form of life like described by a Von Neumann machine would spontaneously come together is below 10^-1000. Dembski’s universal probability bound is 10^-150 (the event will not happen).
But I note some other obvious problems:
· Vital ‘building blocks’ including cytosine and ribose are too unstable to have existed on a hypothetical prebiotic earth for long.
· Building blocks would be too dilute to actually build anything, and would be subject to cross-reactions.
· Even if the building blocks could have formed polymers, the polymers would readily hydrolyse.
· There is no tendency to form the
high-information polymers required for life as opposed to
random ones.
· Dr. Sutherland's reactions producing cytidine do not supply any explanation about how the Chirality problem is solved.
· Self replicating molecules can not replicate for long periods of time without running into second law problems…fuel source. (

· RNA building blocks do not form RNA in the presence of water.

The Bible provides an explanation. But this explanation (e.g. all animals and plants being created over a short time span in their modern forms) doesn't tie in with evidence, e.g. fossil evidence, biochemical evidence. Etc. Hence when evaluating which theory is our current best explanation of how life got to where it is today, the Bible's account doesn't explain things as well as evolution. Even if evolution doesn't explain absolutely everything perfectly.
I disagree there is not credible evidence for evolution in fossils or even a molecular mechanism in biochemistry. When real numbers are applied to chimp human divergence, there are not enough real mutations to demonstrate a 5 million year time line. As time goes on and real investigation of the genome advances, the possibility of common descent weakens. The problem is not that the explanations are not perfect the problem is the explanations don’t work.
Another major flaw in the Bible's account is that it doesn't explain where God came from, and you need God before you get creation. So, the totality of creation by God is largely unexplained.
Except God is displayed in his Creation Romans 1:20.
I would say that there is plenty of evidence for evolution. Similarity of morphology. Similarity of DNA and other biochemical properties.
When you apply the two concepts together; Morphology and genetic similarity a surprising discordance is observed. This fact is a real deficit to a comprehensive explanation of common descent.
The chemistry fits. Current chemistry would support abiogenesis starting with self-replicating proteins, or the RNA world. You say that these don't fit, but can you support this statement. Prions are an example of a self-replicating protein. We're still learning how RNA can form biologically active forms. So we don't need a new chemistry, we need an understanding of how the first proto-life formed, and known chemistry is entirely feasible. This doesn't mean of course that self-replicating proteins or the RNA world are what actually happened, just that they are among the possible explanations. We don't have a known sequence that leads from non-life to life, but we have nothing that suggests that this sequence is impossible.
Chemistry is understood by science today but there is no innate intent in chemistry to form life as demonstrated by Dean Kenyon an authority in the field. Self-replicating RNA and self-replicating proteins still need the basic Teleonomy to function even after you present some solutions to Chirality and natural occurrences of deoxynucleotides and ribonucleotides

The main mystery at present seems to be the lack of time, that cellular life appeared too quickly on earth after life on earth became possible. (At least as far as we understand "possible"). This doesn't disprove abiogenesis. It must means that either the path to cellular life forms was far shorter/quicker than we currently imagine. OR that life came from space, with Mars and distribution of life from Mars through spores in meteorites being one possibility. If that happened, then a wet fertile Mars provides billions more years for the development of early life.
Time has always been the friend to the evolutionist but is nowa problem in common descent. Life starting on a warm earth in stagnate pools of organic sludge is just a fantasy as I explained by the “Faint Sun Paradox”.
Personally I don't like the theory of life from Mars. But currently I have to grudgingly accept that the evidence is weighing in its favour (or other life from space theories).
Mars as far as we have discovered is as sterile as a Petri dish. Cytosine is a component missing from meteorite evidence amongst other essential chemistry of life.
Again, how has anyone shown that spontaneous abiogenesis is impossible?
By observation, Information theory and experimental evidence.
At one point we didn't understand how bumblebees flew, with "current scientific understanding" suggesting that it was impossible. This just mean that we'd identified something that we didn't understand, and subsequent research discovered the mechanisms.
The possibly that a Bumblebee could not fly did not reach the minuteness of the possibility of abiogenesis. An astoundingly small number of 10^-1000.
At one point we didn't understand about microbes or how infectious diseases spread, and came up with all sorts of odd theories. Eventually we learned, and now have a good understanding.
At one point Darwin considered the cell as a bag of protoplasm and he fathered evolution.
IMHO we're at that point with abiogenesis. We know that something happened, but are still trying to work out how it happened.
Your post is entirely reasonable and polite. But can I point out that you're not discussing evolution at all in your post. You're discussing abiogenesis. Evolution is a process by which some life forms can evolve (including splitting) into other life forms. It says nothing about where life came from in the first place. Abiogenesis is an entirely different process/field. Evidence for or against particular theories of how life got started says nothing about evolution at all, because evolution makes no assumptions about how life got started in the first place.
I am trying to group evolution and abiogenesis because I fell that one is an empty explanation without the other as Huxley once thought.
