Pure logic does not include axioms like “you need to breathe or you don’t”, nor does logic lead from the axioms “not all beings need to breathe” and “you can’t breathe in space” to conclusions such as either “all creatures who breathe cannot survive in space” or “no beings who can survive in space are able to breathe.”

A and not-B does not lead to if-not-B-then-A.
That’s a much better argument to make.
