Unless you mean that Earth actually does have something to fear from us (the rest of your post suggests that's not what you mean), then I assume you intended to write either "I don't think Earth has anything to fear ..." or "I think Earth has nothing to fear ...".

I made a mistake (obviously). I would be happy with either of your choices. (I'm pretty sure I meant to say anything but instead said nothing.)

Two negatives should repel...
