Explain Like I'm 5

Gravity is like a big hug from the Earth! The Earth is a big ball, and it wants to keep everything close to it, like a big hug. That's why things don't go floating off into space when you drop them. The Earth's hug pulls them back down to the ground.

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 gravity! It's like the Earth is saying, "I love you, ball! Come back here and play with me!"
