According to George Berkeley's "Essay towards a New Theory of Vision" (1709), he states that there can be no "sound, or figure, or motion, or color, to exist without the mind." He was an immaterialist: matter does not exist. He accepts the position that ordinary objects are composed soley of ideas.

That being said, basically we interpret objects as whatever our brain wants to interpret them as, and every human is different. What I see as a bird, your brain may see a spinning disc...

Very creative theory, but a bit far-fetched to me...

More far fetched that Aliens from a different planet visiting Earth?

Not to mention coming all this way and not even saying "What's Up Earthlings"

Seriously?

I didn't say I believe in that theory, did I?

Last time I checked, most of Bishop Berkeley's philosophical ideas had passed out of currency;
"Esse est percepi" depends wholly on someone observing the universe in toto constantly and can't hold up if you can't prove a god (which nobody ever has, conclusively).

That idea only works if the item is unrecognisable to begin with, 99% of humans with a normal perceived set of life experience would all recognise what an item is or have a pretty good 'guess' at it, for others the brain creates what it wants it to see as the person overrides the obvious recognition sets.

ie, there are people who so badly want to see a ufo etc that they brainwash themselves..

Personally I think his theory 'blows chunks' to use a US term...
