Why Do Infinity and Beyond Exist?

Imagine you have a bag of marbles, no matter how many you take out, there are always more in the bag. That’s like infinity! When we talk about infinite sets, it means some groups of numbers never end, and they can even be bigger than other infinite groups. For example, the numbers 1, 2, 3, ... go on forever, that's one kind of infinity. But there are also more complicated ones, like all the numbers between 0 and 1, that’s a different kind of infinity! It might sound magical, but it’s just math working in a really cool way.
