You do realize that the best place to hide something is in plain sight. If what this guy says is true and a lot of this coincides with what was in the movie Prometheus then why could it not be plausible? I mean where would be a better place to hide something then in a movie. Everyone that watches that movie is going to assume that the movie was "Thought up" by the writer and believe it to be fiction, then when a someone comes along and says no that wasn't his "thought up" creation, it is fact, this really happened, people look at them like their crazy and the people that wanted to keep the secret wins...
