Canon

I don't see how atmospheric elements (oxygen, nitrogen are the main components) have to be tied to biomatter elements (carbon)? Our atmosphere existed before (carbon-based) life began.

Wasn't the Earth's atmosphere initially toxic? I thought it only became breathable after microorganisms produced oxygen as a by-product and gave birth to the biosphere.

That's something that bugs me... there are people in fandoms that like to rant on, to seriously evaluate, justify or question the plausibility of a fictitious story and its plot devices, but then turn around to say that it all shouldn't be taken seriously when more plausible, opposing science or theories are brought in to it.

There's canonical or continuity logic, and there's scientific logic -- and the two don't always go together. As I said before, when reading or viewing science fiction and fantasy, the audience suspends disbelief for a lot of things. But there are limitations to this. While audiences can suspend sufficient disbelief in mass-shifting to believe that a robot full of mechanical components can transform into a car (where did all those internal robot parts go?) - they may not be able to do the same in believing that a giant robot can transform into a small hand held pistol or walkman.

And different audiences have different tolerances of disbelief... those with zero tolerance are most like those who just hate scifi and fantasy and won't have anything to do with them.
