Explain Like I'm 5

Gravity is like a big hug from the Earth! It's a magic that pulls everything towards the Earth, so we don't float 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, pulling it back down to the ground. And that's what gravity does to everything, even you! It keeps your feet on the ground and prevents you from floating away. Isn't that cool?
