Because the frictional force must be greater than forces that would cause the object to move. Example: a car parked on a slope does not move despite the force of gravity acting to pull it down the hill. Why? Because the frictional forces are greater than the forces of gravity.
Stationary friction is the force of resistance that opposes motion between two surfaces in contact when there is no relative motion between them. It occurs when an object is at rest and you try to move it, but there is not enough force to overcome the static friction.
A stationary object does not experience friction if all external forces acting on it are balanced. Friction only comes into play when there is relative motion or an attempt to move the object.
Static friction typically has more friction than kinetic friction. Static friction occurs when an object is not moving, and the friction force is at its maximum to prevent the object from moving. Once the object overcomes static friction and starts moving, the friction force decreases to kinetic friction.
Static friction must be overcome to start movement of a stationary object. This is the friction that exists between two surfaces that are not moving relative to each other. Once the static friction is overcome, the object can start moving.
The four types of friction are static friction (when an object is stationary), kinetic friction (when an object is in motion), rolling friction (when an object rolls over a surface), and fluid friction (when an object moves through a fluid like air or water).

Static
Static friction must be overcome to start movement of a stationary object. This is the friction that exists between two surfaces that are not moving relative to each other. Once the static friction is overcome, the object can start moving.
That is called static friction.

Yes, the force of static friction between two stationary surfaces remains constant until the maximum static friction force is reached. It is equal to the force applied to the object up to a certain limit, at which point the object will start to move, transitioning from static to kinetic friction.
overcome
If an object is stationary on a surface then the forces acting on it are the Gravitational force and the Normal force(the force of the surface pushing back against the object). Technically you could be pulling(or pushing) that object from opposite directions with equal forces and it would remain stationary. The important thing to understand is that a stationary object remains stationary so long as the net forces applied to it equal zero.
Yes, an object can experience both static and kinetic friction. Static friction occurs when the object is stationary, and kinetic friction occurs when the object is in motion. The transition between the two types of friction can occur when an external force is applied to overcome the static friction and set the object in motion.
