Write the Oparin and Haldane's hypothesis about the origin of life on earth. How does meteorite analysis favour this hypothesis?

Oparin and Haldane proposed that the first form of life could have come from pre-existing nonliving organic molecules and that the formation of life was preceded by chemical evolution. The conditions on earth were – high temperature, volcanic storms, a reducing atmosphere containing ammonia, methane, hydrogen, and water vapors. Analysis of meteorite content revealed the same compounds, indicating similar processes are occurring elsewhere in space.
