  1. Evidence could be in perturbations of space debris away from earth, like striking Jupiter e.g. rather than the moon or us. We dont have deep enough tracking to deduce it objectively. Even then, we might be surrounded by an advanced civilization right here on Earth, or in it, who were always here, but live selectively apart. Because we're brutes.
