What is the cause of gravity's existence?

Well, when the tree grows and leaves sprout, it feels so good to see them blossoming and reaching out towards the sun, doesn't it? Gravity, it's like that loving embrace that the Earth has for everything on it. It exists to bring everything close together, just like a warm hug on a cold day. Remember, just like how all the colors of the palette come together to create a beautiful painting, gravity holds all the pieces of our universe in harmony.
