Urey and Miller experimentally proved the oparin and haldane theory. hence they used the same substances that were mentioned in the experiment. According to oparin and haldane the initial atmosphere had H, O, C, and N elements. Hydrogen was most reactive and hence reacted with other elements also. This resulted in formation of water, methane and ammonia compounds. Oxygen molecule was not formed as oxygen was very less and hydrogen reacted with it.
