DAVID: No need for oxygen at all:

"Some microbes have developed the ultimate stripped-down diet. They do not bother with food or oxygen. All they need to survive is pure electrical energy.
"Not bad for simple single-celled organisms

David's comment: Perhaps this is how life started? Note how Archaea work with the electron eaters Very long article. Worth reviewing all of it since there is much more info about different life styles.

Quite mind-boggling! These simple single-celled organisms appear to be able to change themselves at will to cope with whatever environment they encounter. Some folk might even say their sentience, cognitive skills and decision-making are evidence of intelligence (possibly designed by a God), but others will say they are just machines into which a God preprogrammed every single solution to every single problem throughout the history of life.
