: What exactly causes objects to stay on the planet?

Gravity is the force that holds us on the earth, and gravity eminates from every mass including your own body. To answer your question: "What causes gravity? We don't know, if we did we would have a unified theory.

Is it the rotation of the planet?

No the rotation of the planet is trying to throw you off.

If so, how fast would a singularity be rotating to create a black hole?

Current thinking is that black holes are formed by the gravitational collapse of a massive star. A singularity (if there were such a thing) would be the result of the black hole forming, not the other way around as you seem to imply here.
