Explain Like I'm 5

Gravity is like a big hug from the Earth! It's what keeps you on the ground and what makes things fall down instead of floating off into space.

Imagine you have a ball, and you throw it up in the air. What happens? It comes back down, right? That's because the Earth is giving it a big hug with its gravity. The Earth wants to keep the ball close, so it pulls it down.

Gravity is like a magic string that pulls everything towards the Earth. That's why you don't float off into space when you're standing on the ground. It's like the Earth is giving you a big hug too!
