There was a time when I would have indulged this kind of theory, but since discovering that mainstream science failed to mathematically sign energy, so as to enable us at least to discriminate between destruction and creation, and still mainstream science ignores this, despite it being now immediately existential, insisting on carrying on masking it with the very deceptive terminology of "renewables", carbon footprint, despite the atmosphere being adiabatic therefore not capable of supporting any blanket effect, I have to conclude that the greatest evidence of us being extraterrestrial is this very same ability of us to ignore the physical reality right under our nose, the reality of Earth. How can we be so ignorant of the basic physics of this system, if we came from it? It isn't possible to rationalise this imho, except if we say maybe we really did come from Mars or some other planet that was destroyed.
