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 what the Earth is doing to everything on it, including you! The Earth is like a big ball, and it wants to keep everything close to it, so it pulls on everything with an invisible string. That's why you don't float off into space when you're standing on the ground. The Earth's gravity is giving you a big hug, keeping you safe and sound on its surface!
