Gaia freaking loves humans. Even though we're fucking up the environment we're not directly damaging her, just everything that lives on her. So long as we don't do something stupid and kill our selves off like idiots, she's happy to leave us be. And honestly? She's been enjoying modern human entertainment.
As in, she's an avid Spacebattler, plays Warhammer 40k, and a lot of other stuff of similar bent as well.
The problem with that though is a number of shows she saw where Humans somehow get turned into some kind of ultimate being gave her ideas. Good or bad is up to debate.
So how did Humanity take learning that they are essentially her weapons against any and all foreign invaders?
