Explain Like I'm 5

So, you know how things have weight, right? Like your toy car or your favorite book?

Well, gravity is like a big hug from the Earth! It's a magic string that pulls everything towards it, including you! That's why you don't float off into space when you're standing on the ground.

Imagine you have a ball, and you throw it up in the air. What happens? It comes back down, right? That's because the Earth is giving it a big hug with its gravity. And it's doing the same thing with you, keeping your feet on the ground so you don't go flying off into space!
