In 1953 SL Miller created primitive earth conditions in the laboratory and gave experimental evidence for origin of first form of life from pre-existing non-living organic molecules. The primitive earth conditions created include
low temperature, volcanic storms, atmosphere rich in oxygen
low temperature, volcanic storms, reducing atmosphere
high temperature, volcanic storms, non-reducing atmosphere
high temperature, volcanic storms, reducing atmosphere containing $\mathrm{CH}_4, \mathrm{NH}_3$ etc.
