cetripital is spining and the earth has mass gravity

Gravity is a fundamental force exists between 2 objects. Here the earth and you for example. Earth attracts you and you attract the earth. That is gravity. Gravity is not unique to only earth. It is universal force exist between 2 objects.
Centripetal force is due to motion. When a body is in motion it will go in a straight line unless an external force is applied to that body. If you watch the fighter plane or any flying plane when they turn they bank the plane. The force that created when they bank is the reason for the plane to turn. If no banking the plane will go straight even the pilot turn the plane in the cockpit. This external force that is applied to a body to change the direction of motion is called centripetal force. Usually when the body is in circular motion this force is calculated. When a car is taking a u turn etc.

Centripetal force is whatever force is responsible for maintaining an object in an arc or circular motion. Cf is the tension in a string, when spinning an object in a circle on a string. Cf is gravity when the earth revolves the moon around the earth. Cf is friction, when a car turns on the flat road. Cf is not any one particular force in nature. It is whatever force or combination of forces that act along the radius of the circle (or arc).

we use 'centripetal force' for objects which are moving around the earth and 'gravity force ' for the ones which are either moving around the earth or not

centripetal force is acted only when a body is spinning and gravitational force is a mutual force of attraction between two bodies .centripetal force is self acting force

gravity pulls you down
centrifigal..pulls you out, for example when you take a sharp corner in your car
