I am looking for the title of a movie I saw on the Sci-Fi channel years ago.
The plot is that a military man at the beginning asks his commanding officer about why UFOs are downplayed and is told it is because of the panic it could cause. For some reason, he helps the child-like alien escape and shaves his head bald. The alien eats mushrooms and when they finally get to the ship, the soldier finds out that the ship is actually from Earth's future and the "alien" is what we will evolve into. Because the environment is so different, the alien dies.
Later when the CO asks if the soldier will tell anyone he responds with:
What am I going to tell them? That we will evolve into child-sized greys that eat mushrooms?
