ELI5: How is the internet able to work... like that? How are we able to store so much on the internet and stay connected almost seamlessly?

The concept of the internet is always so bizarre to me and It's still a little hard to understand. How is it able to store so many things and have it be accessible to everyone? How are we able to be connected so quickly?

Companies like amazon are where most of the "internet" is. In short, the internet is just a giant web that connects a bunch of computers together. Just like you can search through your own computer files to find the song you're looking for, you can search through "other peoples computers" to find webpages like facebook and the such. 

Internet companies like comcast are laying down physical cables that are doing the physical connecting of computers. It's part of why internet costs so much - those companies are constantly laying down more cables or new cables, and that costs a ton of money.
