prologos - was it not about the transition from dead matter to life? and we have not just mud, but organic, ex-life stuff around. Is life then a question of oxygen management?
Ah, yes you did mention restarting life. I don't know what the obstacles are, but I suspect it's a lot more complicated than just oxygen management. I'm a complete lay person in this area, but I suspect a big part of the answer is entropy--if for no other reason than entropy rules all. If anybody asks a science-ey question that you don't know the answer to, just say "entropy" and there's a good chance you'll be right.
