It is simply one way that it did. Scientists do not know how life began on Earth, but they do know that the early Earth’s atmosphere was very different from the atmosphere now.In 1952, Stanley Miller was working with Harold C.

Deep sea vents, or "black smokers" as they are often called, occur at oceanic ridges where new sea floor emerges from the Earth's mantle. Scientists believe that some of the earliest life on Earth may have formed around these vents when chemical rich material from within the Earth poured into the oceans. Today's "vent communities" include tube ... But there are many theories. The area of science to look at is called abiogenesis . Another way of looking at things is that "life" is really no different from "non living compounds".
