I still assert that they have a vested interest in Humanity.
We, humans, Use Animals to our benefit. Whether we use them as pets or entertainment or even workforces on farms.
I suggest. That there simply wouldn't be an interaction between us and they unless they were using us to their benefit somehow. We for as much as we love them, Keep pets for selfish reasons, We don't do it for them, We do it for Us. And when they pass, We Hurt. But we don't hurt for them, We Hurt for our own loss, Their suffering is over and to wish them to be back and continue to suffer is a display of our own selfish desire. They may be alien, But, Nature is something that's universal, They arent here interacting with us to better our lives, The proof in that is, how great are our lives exactly? a Supposedly technologically advance species with cloning capabilities and knowledge that could cure most diseases and end wars, Yet we still suffer and die, And kill. They could help us, But seemingly they have never once done this. They are here for their own benefit, That seems clear.
