First, in your OP you said that the Miller experiment was used as evidence to support Evolution.
Many people here have pointed out to you that it has nothing to do with Evolution. Evolution deals with what happened after life formed, not with how life formed.
Second, you have claimed that the experiment failed and the reason you claim it failed was that a later experiment produced cyanid. Well, again, people have pointed out to you that there are critters that live in such an environment.
How life started is still very much an open question. But it is also one that will very likely be solved during your lifetime if not mine. The Miller experiment was from 50 years ago and much has happened since then.
In summary, the Miller experiment has nothing to do with Evolution or the Theory of Evolution. Even if it is totally wrong it has no effect on the TOE.
