It's pretty dumb to just write something off as not real.
Gorillas were not even widely known about in the english speaking world until the late 19th century.
It's fucking retarded to emphatically state that aliens aren't real, since the universe is so big you can't even comprehend it.
Also, History channel will never go back to showing "real history", since, as a television channel, they survive by generating ratings that interest advertisers.
