The Fourth kind real or fake?

ok so i was watching the fourth kind i was so confused. ok so here's the deal i know Dr. Abigail "Abbey" Tyler was played by actor and her name and career was change to get her identity a secret as. i was watching a part of the movie when tyler place a guy in hypnosis and he floated off the bed in the movie and in the archive footage and his voice change to something non-human yet no body thinks that ufos are real. come on how much proof do you need the freaking aliens where talking to her in both the archive footage and the movie how can that be explained? also i don't understand how no body said the word Alien to the end of the movie. i will still continue my research on this.
