Not Aliens..
Aliens are nonsense made up by Governments of the world in order to gain more control over the people. One day, when most everyone believes this crap they will stage some event and claim they need complete control to solve the problem.
There are however demons, often confused as aliens because Satan will claim anything to keep from admitting he is Satan. :)
