Expression denotes a `method group', where a `variable', `value' or `type' was expected

Hi, so I started working on the AI attack function, I am having some problems tho, in the last line of this part of my script:

 void Attack () {
         RaycastHit hit;
         if (Physics.Raycast(transform.position, transform.forward, out hit)){
             if(hit.distance <= minimumDistance && hit.transform.tag == "Player"){
                 hit.collider.gameObject.GetComponent<Player>.health -= damage;

in the last line I am getting this error: Assets/Scripts/AI/EnemyMeleeAttack.cs(31,57): error CS0119: Expression denotes a method group', where a variable', value' or type' was expected, it's not the first time I have this error, I had it in one line that is above:

         GameObject tempClosestEnemy = gameObject.GetComponent<EnemyScript>().closestPlayer;
         if(Vector3.Distance(transform.position, tempClosestEnemy.transform.position) <= minimumDistance){

but I fixed it creating the temporary variable to store the value, it worked (btw is the var type supposed to be GameObject?) so in the line that I am having the error I also tried making a temporary variable (GameObject type) to store it, but I was getting this error: Assets/Scripts/AI/EnemyMeleeAttack.cs(31,87): error CS0119: Expression denotes a method group', where a variable', value' or type' was expected in the temporary variable line, and this error: Assets/Scripts/AI/EnemyMeleeAttack.cs(32,33): error CS0019: Operator -=' cannot be applied to operands of type UnityEngine.GameObject' and `int' in the second line:

             GameObject tempPlayerHealth = hit.collider.gameObject.GetComponent<Player>.health;
             tempPlayerHealth -= damage;

help me please! and thanks in advance
