The approach which currently is proving to be the most promising in determining how life on earth originated is the laboratory simulations of conditions present on the early earth.
The conditions that were present on the early earth were:
The laboratory simulations of conditions on early earth was a chemical experiment named as Miller-Urey experiment, which in 1952 simulated the conditions that were present on the early earth.
In 1952, Stanley Miller and Harold Urey simulated the conditions of early Earth by sealing water, methane, ammonia and hydrogen in a glass flask. Then they applied electrical sparks to the mixture.
