If your up in an airplane and its going fast, have you ever wondered why if you jump up in the air, the airplane doesn't take off from under you feet. That is because you as the person in the plane are both traveling at the same speed through the air. Gravity just keeps spinning the universe around and that keeps everones feet securly on the ground, even in a trans-atlantic jet.

Jump off a chair and you'll see.
Okay, okay, I'll tell you. The core of our planet behaves like a huge magnet, therefore everything that is on Earth is attracted by it. This is why we can only fall to the ground, but it's not the ground that attracts us, it is the magma inside of the planet which, by rotating, creates a magnetic field. Basically, the bigger a planet or a star is, the greater the attraction force generated by it, is.
