so,,,is there any proof that UFOs are space visitors?....no

There is nothing to support such ideas.
All there is that is "called proof" are campfire stories.

all the photos of UFOs are always fuzzy.

No person ever stood up with something in their hands and said., "its from a spaceship"

Nope....all they got are some spooky stories to tell around the campfire while drinking some beers, and fuzzy photos.....
