JBS Haldane and Alexander Oparin speculated that conditions on the early Earth were favorable to making complex organic compounds from simple inorganic precursors. Stanley Miller and Harold Urey tested this by mixing gases that could have been part of the early Earth's atmosphere, at least around a volcano, carbon dioxide, nitrogen, hydrogen sulfide, and sulfur dioxide, and adding energy. Even if amino acids had been a specific target (and I don't think they were, it was just an attempt to see if more complex organic chemicals would form), I wouldn't call that design. I think just reading what you wrote there, it's obvious Miller and Urey had a target and designed their experiment to get the target. I would call that a designed experiment. BTW, Miller and Urey's ideas about the early atmosphere have, I think, been shown to be offbase. Though I don't that's important since I don't consider amino acids that significant. Like wood pulp and books. There's a relationship, but the wood pulp is just the medium information is recorded on not the source of the information in the book. Other later versions of the experiments have produced more than just ammino acids. Substances produced include sugars, nucleotide basis (building blocks of DNA and RNA), alcohols, aldehydes and organic acids. CO2 is "organic" in the sense of organic chemistry. It has carbon atoms; but its simple, and common both where life is present and where there is no evidence of life. Edit - Or maybe not - "For historical reasons discussed below, a few types of carbon-containing compounds, such as carbides, carbonates, simple oxides of carbon (such as CO and CO2), and cyanides are considered inorganic." https://en.wikipedia.org/wiki/Organic_compounds Organic, inorganic ... life is composed of natural substances. Just as books, programmed computer chips are. The substances themselves aren't the big thing.
