@withoutlimits09 - It's funny how 2 people can hear the same thing and have different opinions of how it was. I do not for one second think that Chris or Gene were actually laughing at the idea of the ETH. I do not think they discount it either. It's just we have insufficient tangible evidence to convince many people that there really are non-man made craft in our skies. Even though we have photos etc of UFOs, we don't have photos of any occupants and we most certainly do not know if any possible UFO occupants actually come from another planet.
Even Randall (Ufology) would concede that the ETH is really arrived at by process of elimination, that is, we work out that it might indeed be the most
probable hypothesis. It isn't because we have solid proof the ETH is the answer. Unless you can supply proof of who UFO occupants are and where they are from, we can only guess until then.
Some people believe that a great power may be masquerading as ET's visiting in ships, some believe it is a crypto-terrestrial race.
