That experiment not only failed but is now known to have been based on incorrect assumptions...correct?
It worked for them because Urey assumed a lot of methane and you know what that is, fartsmoke. Farts are comprised of
The problem for them was oxygen, O2, so they left it out. Try the experiment and add some oxygen to see what happens.
- Nitrogen: 20-90%
- Hydrogen: 0-50% (flammable)
- Carbon dioxide: 10-30%
- Oxygen: 0-10%
- Methane: 0-10% (flammable)
Many scientists do not think these were the gases of the early universe, but volcanic gases.
"The primary components in volcanic gas are water vapor, carbon dioxide and sulfur (either sulfur dioxide or hydrogen sulfide). But you can also find nitrogen, argon, helium, neon, methane, carbon dioxide and hydrogen."
The rub is with these gases amino acids do not form.

Actually, the rub is that amino acids do form and they form as conditions change.
“The primary components in volcanic gas are water vapor, carbon dioxide and sulfur (either sulfur dioxide or hydrogen sulfide). But you can also find nitrogen, argon, helium, neon, methane, carbon dioxide and hydrogen."
Gee whiz, what a coincidence those chemical compounds are among those elements that scientists call “building blocks of organic life”.
