Right, right, but if, like Alex stated, the flame is extinguished after the destruction of Asgard and subsequent death of Sutur, that'd make collecting it impossible. As far as I'm aware, the Eternal Flame was likely created after the Infinity Stones were, since they were among the first things created in the universe.

And, if Sutur's corpse is in space (key word being "corpse"), then the Eternal Flame would have to be destroyed since Sutur would be dead
