About those aliens from other worlds landing on earth..I have a theory..
About 65 to 70 years ago, they landed and gave to the earth, a person they created, who they called .."Donald" and he somehow managed to hook up with a real rich family. That family was the Dumps, but they changed their name to Trump..Now, that small child was raised by that family, but the aliens, and I don't know what star, or part of the galaxy they came from, have been keeping track of their planted person, and they will use that planted alien to......
...take over the world.......
Now, you may not believe that one, but I saw it on a show called, Animaniacs, which was partially created by that Steven director.....you know, he did movies called, Lincoln, ET and Close Encounters.." ...so it must be true...
Now..of course you do not believe one word of this..ok, so here is a link that says they are bringing back Animaniacs for another round of TV shows.. And guess who is making that happen..that Stephen fellow who directed ET, Jaws, Lincoln and Close Encounters...here is the link:

if the aliens were say 1000 years ahead of us....then they could do it...Look where the people on earth were a thousand years ago....called the "dark ages"...Let's say that that planet that dropped that kid 70 years ago, was 1000 years ahead of us, and that planet had no .."dark ages" so who knows what they could accomplish???
If we could go back 1000 years, and talk to some intelligent educated people, would they believe what has been accomplished??? and .."Who knows what evil lurks in the hearts of men?"......the shadow knows...
oh no....................got to go back to 
Explains why nothing they say makes a damn bit of real sense.
and the increase destructive attitude sounds alien as well.
TV show that got lost in the closet. Now Stephen the director found it, and will bring it back soon. And Alf will be back too ..and he does indeed like KFC. And there is more coming..but truly, it really is time for me to go and hide.............cause they are coming to take me away..eh ha ..............
