I seem to encounter many litreture ( where mostly Advanced AI's or Alie'sn decide) that Humanity must be annihilated in order to save Earth.

Even though Earth is really unique (with radiative cluster, giant moon, appropriate distance from right class star etc.) to let evolution and there may not be a second one (?) among 'Earth like' planets, I can't help to think that an intelligent life form such as Humans should not be more common than Earth.

And since many choose to kill Humanity rather than Earth in their work my question is: Is really Humanity more expendable then Earth scientifically or is it just to create a melodrama of justified punishment of our greedy nature and discovering/showing ourselves that we are more than that?

PS: Not sure if this question is more fit here than a science based network.

    Not sure if any SE site is suitable for this question. But there's plenty of people down my local boozer that will happily discuss this with you after a few pints. – Moogle Nov 14 '17 at 10:37
  • There are so many, and question is more like is the idea belongs to fiction or science. – ifyalciner Nov 14 '17 at 10:39

    @atayenel - It's a good question, but a terrible fit for SFF:SE. Questions about the tendencies of real-world science fiction writers aren't on-topic here. – Valorum Nov 14 '17 at 10:47

    @Valorum this question might be suitable for worldbuilding with a little editing. Why my AI prefers human extinction rather than earth ? kind of editing – atayenel Nov 14 '17 at 11:56

    @atayenel - As written, it'd get closed on WB almost immediately. It's too vague and too poorly written – Valorum Nov 14 '17 at 13:16
