So....

Have you guys ever wondered if things that you don't see continue to exist or not? well I have a presentation about this, and this is very interesting. How do you know that things that you don't see continue to exist? how do you prove it that it exists? Well if you guys want to dig deeper into this, I suggest you look up ''idealism by George Berkeley''. you'll understand more.

one more thing, try to understand what this means

''to be is to be perceived''
-george Berkeley
