Explain Like I'm 5

Gravity is like a big hug from the Earth! The Earth is like a big ball, and it wants to keep everything close to it. So, when you drop something, like a ball or a toy, the Earth gives it a big hug and pulls it back down to the ground. That's why things don't float off into space when you drop them. The Earth's hug keeps them safe and sound on the ground. And that's gravity!
