Historically, it was widely accepted that obligate (strict) anaerobes die in presence of oxygen due to the absence of the enzymes superoxide dismutase and catalase, which would convert the lethal superoxide formed in their cells due to the presence of oxygen. While this is true in some cases, these enzyme activities have been identified in some obligate anaerobes, and genes for these enzymes and related proteins have been found in their genomes, such as Clostridium butyricum and Methanosarcina barkeri, among others. However, these organisms are still incapable of growing in the presence of oxygen. There are several hypotheses addressing why strict anaerobes are sensitive to oxygen.~ thanks wikipedia
In theory the first living creatures would have lived in an oxygen ABSENT atmosphere, then the first green plants appeared (most likely Algae), which would have killed all of the first living things on earth, in a cataclysmic life and death conversion. (water being H2O, and oxygen brought death to everything creating whole new carbon base life forms that survive in an oxygen rich atmosphere) (5 years and 3222 days ago)
