I'd like to know the cellular science that explains the formation of a single cell organism. It should be step by step or a good reference to the reactions that occurred to form a single cell organism. The actual scientific reactions only please.

Why did you think that atheists would know the answer...? There isn't one that they know. God is the answer. And this should be in the R&S section sillies. I'll try to stop laughing at atheists but they are so funny!

unknown. and you must know that it's unknown, otherwise you would ask this question where you could actually expect to get an answer, in the science section.
there are various approaches to the problem of abiogenesis. identifying ancient biochemistry by looking at modern organisms seems a bit daunting as there is so much biochemical diversity within the bacteria and more is being discovered all the time. but this is in some ways the best way to go, because there is almost no evidence forthcoming from ancient rocks, most of which are long since destroyed by erosion and plate tectonics. i rather like the idea that life originated with chemautotrophs at deep ocean vents - although that may turn out to be wrong, it does at least suggest avenues for research.
no doubt you wish to stuff your god into this gap in our knowledge, and claim that the problem will never be solved, in the best tradition of religious nihilism. this is not a good strategy in the long run. turns out that god was not necessary to explain planetary motion, the origin of species, or the development of embryos (among many other things). if history is anything to go by, i expect god will turn out to be also unnecessary to explain the origin of life.

Chemical reactions formed organic marcomolecules
Macromolecules formed nucleic acids
Nucleic acids with the right sequence of nucleobases replicate
A phenotypic RNA world evolves
Chemical evolution proceeds, but with different rules than biological evolution (different shards of RNA can bond together)
Shards of RNA evolve that have as few as 200 codons but can store information, assemble proteins that form a virus-like shell and replicate
*RNA phenotypes evolve codons that assemble proteins and lipids.
.... we are still a few million years away from evolving a cell with chromosomes made of DNA but we are getting there step by step, no?
* there is some lab evidence that protein and lipid metabolism may have evolved apart from RNA synthesis and merged endosymbiotically with RNA
These steps are not just guesses but most have been replicated, at least in large part, in labs at Harvard (Jack Szostack) and Scripps Institute. In fact the process seems so easy that the government is now allocating millions of dollars of your tax money to study the possiblity of life anywhere on another planet or moon (Europa) where water might exist (or have existed). An entire scientific field, astrobiology, is devoted to this. The Journal of Astrobiology is another good source for primary research on abiogenesis.

"I'd like to know the cellular science that explains the formation of a single cell organism."
Then consider a college education in microbiology or chemistry.

Yes, many people would like the answer to this question. Some are willing to use science to search, while others find the idea of a non-supernatural answer terrifying, so they abandon rationality and say, "goddidit!"
I'm happy to wait centuries for science to discover the natural truth, which it eventually will because there is no other possible explanation.

Clay theory is current best estimate. Prions are interesting little things - like life, only not. We don't think. They cause Mad Cow Disease and they're resistant to just about everything (won't burn or be poisoned). More like stone than carbon-based life, yet they have a means of reproducing.
But as Eri said, you'd find out more in a book if you were really interested.

There's ongoing research in that subject, and nobody is quite sure yet. But scientists are working on it.
By the way, if humanity were content to give up the research when confronted with a confounding problem, there would be no Yahoo answers available for you to ask that question...

If you really wanted to know the answer, you would have posted this is in the science section. Not every atheist is a molecular biologist. This one is an astrophysicist.
Since you posted it here, I'll just assume you're planning to keep your ignorance no matter what answer you get.

Our species hasn't figured out all of the answers to the universe.
To help us get there, start by knocking off the nonsense of organized religions. Open your minds and start thinking. Stop encouraging your children to be delusional thinkers.

Why ask atheists? This is a question for scientists. Atheists and scientists are not necessarily synonymous, although there is a strong correlation due to the high intelligence factor.

Some people theorise it was the fusion of subcellular life such as bacteria, that formed simple "cells" almost like symbyosis.
Really quite simple, I am more interested in the first self propelled peptide.
