“If aliens visit us, the outcome would be much as when Columbus landed in America, which didn’t turn out well for the Native Americans.” –Stephen Hawking
If Aliens landed on this planet it would go one of two ways. They would help us at first until we learn they have a sinister agenda and they would destroy us or we would use their technology against them. One of my favorite shows was Gene Roddenberry's Earth Final Conflict. I liked the Talons were both good and evil. It got goofy in those final years but I watched the whole Canadian series. Season One is the best with William Boon trying to discover the hidden Talon agenda. I think Roddenberry had a pretty good view of how an Alien visitation would go.
Oh and if they tasted like chicken. We would Kentucky Fry them so quick that they would still feel their pieces going into the bucket. I'll take original recipe with gravy. Here is what the rest of the League is saying.
