Explain Like I'm 5

Gravity is like a big hug from the Earth!

You know how when you hug your favorite toy or stuffed animal, you want to hold onto it so it doesn't go away? That's kind of like what the Earth is doing to everything on it, including YOU! The Earth is giving everything a big hug, and that's what keeps us on the ground and what makes things fall down instead of floating off into space. Isn't that cool?
