Explain Like I'm 5

Gravity is like a big hug from the Earth! You know how when you give your favorite toy a big hug, you want to keep it close to you? Well, the Earth is doing the same thing with everything on it, including you!

The Earth wants to keep everything close, so it pulls on everything with a special kind of magic 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 keeping you right where you are!
