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 wants to keep everything close to it, so it pulls on everything that's near it.

Imagine you're playing with a friend on a trampoline. You're jumping up and down, and your friend is holding your hand. The Earth is like your friend, holding your hand and pulling you towards it. That's why you don't float off into space!
