Explain Like I'm 5

Oh boy, gravity is like a big hug from the Earth!

You know how when you're playing outside and you throw a ball up in the air? And then it comes back down to the ground? That's because the Earth is giving the ball a big hug! The Earth wants to keep everything close to it, so it pulls on everything that's near it, including you!

That's what gravity is - the Earth's way of keeping everything close. It's like a big, strong hug that never lets go! And that's why you don't float away when you're standing on the ground. The Earth is giving you a big hug too!
