Personally I would like to see references linking Miller with "the existence of an oxygenated environment early in earth's history". If that's what you meant when you said in a previous post, "all planetary scientists (including Miller himself) are now convinced that the atmosphere of the early earth would have made Miller's syntheses impossible", then I have to say I believe you are wrong. To my knowledge, Miller never made such a claim, and neither did any but very few planetary scientists who are not creationists.
