Explain Like I'm 5

Ooh, gravity is like a big hug from the Earth!

You know how when you give your favorite toy a big hug, it feels like it's being pulled towards you? That's kind of like what the Earth does to everything on it, including you! The Earth wants to keep everything close, so it pulls on everything with a magic string called gravity.

That's why you don't float off into space when you're standing on the ground. The Earth is giving you a big hug, and it's keeping you stuck to the ground. Isn't that cool?
