The theories are, the primordial soup/replication first hypothesis and the hydrothermal vents/metabolism first hypothesis. In my own opinion, I would select the Primordial Soup Hypothesis because it gives a clearer explanation that is based on tangible arguments.

The experiment actually brought to light that theories about the evolution of life could be actually tested in the laboratory. According to the theory, the earth in the early contained large amounts of methane and ammonia gases which reacted to form amino acids which are the building blocks of proteins. The theory was questioned by scientists who argued that the amounts of gases used ...
