Explain Like I'm 5

Gravity is like a big hug from the Earth. The Earth wants to keep you close, so it gives you a big squeeze. That's why you don't float off into space when you're standing on the ground.

Imagine you have a ball, and you throw it up in the air. What happens? It comes back down to the ground, right? That's because the Earth is giving it a big hug, pulling it back down.

Gravity is like a magic string that pulls everything towards the Earth, keeping us safe on the ground.
