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 pull it close to you? That's kind of like what the Earth is doing to you right now. The Earth is a big ball, and it wants to keep everything that's on it, like you, close by. So it gives you a big hug, and that's what makes you feel like you're stuck to the ground. It's like the Earth is saying, "Hey, I love you! Stay close to me, please!" And that's gravity!
