Explain Like I'm 5

So, you know how things fall down when you drop them? Like if you drop a ball, it falls to the ground?

That's because of something called gravity. Gravity is like a big hug from the Earth. The Earth is giving everything on it a big squeeze, and that's what keeps us and everything else stuck to it.

Imagine you're playing with a big beach ball, and you're holding onto it really tight. The Earth is like that beach ball, and it's giving everything a big hug, keeping us from floating off into space!
