Harold Urey and Stanley Miller passed mixtures of boiling water, ammonia, methane and hydrogen through elaborate "electric spark systems" of beakers and test tubes. In those experiments, they were able to produce traces of one or two amino acids -- the "building blocks of life" -- and therefore, the media hailed these as proof for the possibility of spontaneous generation (evolution) on a prebiotic Earth.
There were many unreported problems with these "designed" experiments. Dramatically, the greatest byproducts of these soups were tar (85%) and carboxylic acids (13%), both of which are toxic to living systems. Notwithstanding all the other issues, producing a trace amino acid in a laboratory experiment would be similar to producing a clay brick and declaring that we just figured out how to randomly design and build a New York skyscraper.
Take a frog and put him in a blender until frothy. Leave it in the sun for a million years. Do you have a frog? No, still frog soup.

How can you have anything but a soupy mixture containing the building blocks of frog life. With no information code to tie it all together, you have nothing resembling any kind of self-existing organism."
In this simple (yet graphic) illustration, I gave every potential to create a frog. I provided every chemical, amino acid, protein and molecule that makes up the frog's organic structure. However, if I placed this illustration in the context of a "prebiotic soup" on primitive Earth, we'd be lucky to see even one trace element or amino acid develop over the same time period -- let alone the biologic components of an entire frog!
