What are the 4 theorized steps for the creation of cells from non-living matter?

1. Scientists simulated Earth's atmosphere billions of years ago by passing electrical charges through hydrogen, methane and ammonia. Carbon compound and amino acids necessary for life were produced. 2. To turn those carbon compound into polymers, it is thought that energy from deep sea vents was taken. It's where there is hot water gushing out, and where reduced inorganic chemicals such as iron sulphide could be found. 3. To make plasma membranes, a bilayer was formed, where amphipathic carbon compounds assembled vesicles to resemble a plasma membrane 4. RNA instead of DNA might've been used to pass on genetic material, since RNA is self replicating, serves as a catalyst and also stores genetic material
