Right now our universe is this planet. At least that’s how I think we need to start viewing this organic spaceship,.and we do have a profound effect on it. Also, while our tiny planet is an insignificant dot in the universe, you have no way of knowing our significance unless you are an all-knowing deity or can see the future. Maybe we seed and populate the rest of the universe once we get our shit together. Or maybe we blow ourselves up with nukes before we get there. Who knows? I don’t, and I don’t think you can say for sure either.
