I do believe that many UFOs are under intelligent control.  Some say ETs 
became interested in the US as the nucleara era began.  I can't explain why 
UFO reports mainly come from the US.

I don't believe that all are weather ballons, reflections, stars, jet 
contrails, military experiments, missles, and jets.
I don't believe that all crop circles are hoaxes.

Many people laugh at these beliefs and are too intelligent to argue with, so 
so be it.  Some of it could be involved with my spiritual beliefs, such as 
"does God exist?"
