The Origin of Life
In the past, the complexity of a single cell was unknown. But with all that we know about genetics today, it is inconceivable for anyone to summarize that life could have been created from non-life and assembled by chance.

There is no lack of creative scenarios that attempt to explain how life emerged. What’s lacking is any proof that life miraculously arose by chance:

Is There Such a Thing as a ‘Simple’ Form of Life?
One of the SIMPLEST forms of life is a prokaryotic bacteria cell. The outer construction is made up of a cell wall, a cytoplasmic membrane, and an outer membrane capsule. Its contents include the nucleoid, cytoplasm, ribosomes, and its DNA. It also has a flagellum for movement and pili to help the bacteria attach to other cells and surfaces.

Because cells require several components to exist, how likely was it that each component:
The Complexity of Cells is Staggering:
- DNA and RNA are instructional, duplicate, and highly complex information codes within a cell. DNA acts like the original computer code and RNA acts like a copy machine, repeating and decoding the instructions to each part of the cell:
“DNA carries the genetic information of a cell and consists of thousands of genes. Each gene serves as a recipe on how to build a protein molecule. Proteins perform important tasks for the cell functions or serve as building blocks. The flow of information from the genes determines the protein composition and thereby the functions of the cell … Every cell must contain the genetic information and the DNA is therefore duplicated before a cell divides (replication).”
http://nobelprize.org/educational_games/medicine/dna/index.html
“DNA even contains the instructions to devise the cellular machinery to decode its instructions. Without a mechanism to decode the information, the DNA blueprint would be useless.”
http://www.answersingenesis.org/docs2007/0228dna-secret.asp
- Cells generate their own electrical fields by a current of ions crossing the cell membrane.
“The membranes of living cells, from bacteria to human, contain protein macromolecules that behave rather like field-effect transistors.”

- Seemingly identical cells 'differentiate', each one independently building a specific part of an organism.
“'We still do not fully understand how cells differentiate,' said Thomas Aune, Ph.D., professor of Medicine and Microbiology & Immunology. 'We know that the cell is essentially defined by the genes it expresses. That makes a given type of cell 'that cell' — a nerve cell, a heart cell, etc.,' he said.”
http://www.mc.vanderbilt.edu/reporter/index.html?ID=5669
- Within cells, there are hundreds of various types of high tech miniscule molecular motors that continually read, copy, and continually repair DNA, and, “are involved in everything from muscle contraction, to moving chromosomes during cell division, to reloading necessary ammunition within nerves cells so they can repeatedly fire.”

http://www.news.ucdavis.edu/search/news_detail.lasso?id=6671
- Bacterial cells have a ‘flagellum’ that allows each one to swim independently of another. Each flagellum has a microscopic electrical motor complete with parts resembling a drive shaft, a universal joint, bushings and bearings, a rotor, a propeller, and more. This motor can rotate at over 1000 times per second, change directions and is powered by the voltage difference developed across the cell membrane.
(Paul Boyer of UC Los Angeles and John Walker of the Medical Research Council’s Laboratory of Molecular Biology in Cambridge won a half share of the 1997 Nobel Prize for Chemistry for the discovery of this enzyme/motor.)

Attempting to prove that life arose spontaneously, note that Harvard University’s Origins of Life in the Universe Initiative plans on “adding faculty members and a collection of multi-million dollars facilities.”
If it’s so easy to “reduce this to a very simple series of logical events that could have taken place with no divine intervention," why does it appear they’re in it for the long haul?

"The origin of life is a science writer's dream. It abounds with exotic
scientists and exotic theories, which are never entirely abandoned or
accepted, but merely go in and out of fashion."
—John Horgan
Former Senior Writer at Scientific American (1986-1997) in his book The End of Science: Facing the Limits of Knowledge in the Twilight of the Scientific Age. (Little, Brown, & Co.: London, 1997, p. 138). His awards include the Science Journalism Award of the American Association for the Advancement of Science (1992 and 1994), the National Association of Science Writers Science-in-Society Award (1993) and the 2005 Templeton-Cambridge Journalism Fellowship in Science and Religion.

“Despite considerable experimental and theoretical effort, no compelling scenarios currently exist for the origin of replication and translation, the key processes that together comprise the core of biological systems and the apparent pre-requisite of biological evolution. The RNA World concept might offer the best chance for the resolution of this conundrum but so far cannot adequately account for the emergence of an efficient RNA replicase or the translation system.”
“The cosmological model of eternal inflation and the transition from chance to biological evolution in the history of life” Eugene V. Koonin, Senior Investigator, National Center for Biotechnology Information, National Library of Medicine, National Institutes of Health, Bethesda, MD, MS and PhD in Molecular Biology from Department of Biology, Moscow State University, Moscow, Editor of Genome Analysis section in Trends in Genetics, Biology Direct 2007 2:15.
