The conditions proposed in the Miller Urey experiments never existed.

Explanation:

the Miller Urey experiments proposed an early atmosphere that was similar to what was thought to be the early composition of the universe. The highly reducing atmosphere of Hydrogen Methane and no Oxygen never existed.

The most recent evidence is that what ever atmosphere was formed with the formation of the earth's proto planet was stripped away. The atmosphere of the early's earth's oceans was formed mainly from volcanos. the atmosphere always contained some levels of concentration of Oxygen.

The concept of the primordial soup has been disproved and discarded by most scientists .
