A thought occurred to me. When The Great Tall One consumes the last lives on earth, what will become of his Children? Will he consume us as well? No... That would eliminate his amusement. Perhaps... Adam and Eve... Perhaps he would leave two of us behind, male and female, to ensure the survival of his prey. Meanwhile, perhaps he would go into a state of hibernation until the numbers of his prey are replenished enough to begin the hunt all over again.
Perhaps that was the origin of the original Adam and Eve? Survivors of an earlier hunt?... No... No... Not likely... He could not possibly be that old could he? Then again, he is a supernatural entity with nigh-omnipotent power. How should I know what he can and cannot do?
