- raducu 6y agoRoom temperature does not mean safe for carbon life, I'm sure at a far enough distance from a nuclear reactor's core there's "room temperature". But at that time, there must have been very few heavy elements so any life must have been "plasma life" and "room temperature" probably was very unpleasant for them.
