What Causes Gravity to Pull Us Down?

Gravity is like a invisible string that pulls things together. Imagine you're holding onto a ball, and then you let go, the ball falls to the ground because Earth's gravity pulls it down. The bigger something is, the stronger its pull. Since Earth is really big, we feel its pull every day.
