Explain Like I'm 5

Oh boy, gravity is so cool!

Gravity is like a big hug from the Earth! It's a magic string that pulls everything towards the Earth, including you! When you drop something, like a ball, it falls down because the Earth is giving it a big hug. The Earth wants to keep everything close to it, so it pulls on everything with its magic string.

That's why you don't float off into space when you're standing on the ground. The Earth is giving you a big hug, keeping you safe and sound! And that's gravity!
