Re: A deep thought regarding life out there
Current theory is that life has to evolve on a planet before it can get a substantial oxygen component in the atmosphere. Oxygen reacts with just about everything, so you need life forms to pump it into the atmosphere faster than it can all combine into other compounds. Oxygen breathing life didn't appear until the first blue-green algaes supplied the oxygen.
