Why Darwinism remains hopelessly bound to Spontaneous Generation:
Answer: The Miller-Urey experiment.
This was on the recent SAT 2 exam and is thus considered vital knowledge by the Darwinian community. The Miller-Urey experiment showed that by putting a spark through certain gas mixtures, amino acids would form. Amino acids are, however, the building blocks of proteins and cells have lots of proteins. Therefore, it is implied and taught in biology classes across America, life could have occurred.
The problem here is that the gap between amino acids and a simple, standalone life form that can maintain its structure, feed off of the environment, and reproduce itself sufficiently repeatably to begin an evolutionary process is comparable to the gap between silicon crystals on the beach and a computer complete with microsoft windows. Amino acids can float around in a mixture, but like silicon crystals, they don't combine to form structures automatically. Also, proteins formed from amino acids aren't sufficient to form life by themselves either. They need something more, like DNA and RNA. Similarly computers need something more than silicon crystals.
The Miller-Urey experiment is only significant to an ideology that still believes in spontaneous generation. 100% pure spontaneous generation.
