@dyresand.
Your posts are difficult for me to understand and I believe you have misunderstood some of mine. I don't mean to be rude, but is english your first language?
Artificial abiogenesis
In the 1950s, several experiments by Stanley Miller and Harold Urey verified that the natural formation of amino acids, components of DNA, and other organic compounds out of inorganic materials was possible under the atmospheric conditions of Primordial Earth. Le-Chatelier's principle states that protein synthesis is not possible on water since it requires a condensation reaction. The UV radiations from the Sun would've made it impossible on land. Today, it is generally accepted that Abiogenesis happened in neither land nor oceans, but a combination of both, in mud. Also, the primordial Earth conditions are now thought to be different than those at the time of Miller's experiment, which makes it outdated. "Many scientists now suspect that the early atmosphere was different from what Miller first supposed. They think it consisted of carbon dioxide and nitrogen rather than hydrogen, methane, and ammonia. That's bad news for chemists. When they try sparking carbon dioxide and nitrogen, they get a paltry amount of organic molecules - the equivalent of dissolving a drop of food colouring in a swimming pool of water. Scientists find it hard to imagine life emerging from such a diluted soup" (National Geographic, "The Rise of Life on Earth", March 1998, p.68). There have been, however, more successful, newer experiments based on these conditions. There is only one major problem with Miller's experiment: "How do you make polymers? That's not so easy." (Earth, "Life's Crucible", February 1998, p.34)[7] Comedian George Carlin suggested that making plastics was the reason for the existence of humans. Creationists have "criticized" the experiment due to the amino acids produced being racemic mix, aka being completely useless to life, even though that wasn't the point of the experiment.
