an object reference is required for the non-static field method or property 'Collision.collider'

I’m doing a 2D game and I need to detect collision of an object with a prefab with Ground tag. Here is the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class OvercomeObject : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        
    }
	
	public static void OnCollisionEnter(Collision collision) {
		if(Collision.collider.CompareTag("Ground")) {
			Debug.Log("Collided");
		}
	}
}

Unity says:
an object reference is required for the non-static field method or property ‘Collision.collider’
I was looking for solution, but I didn’t found it. Help please!

@SashaAlexios2007 Instead of having Collision.collider, have collision.collider. Remember, c# is case-sensitive.
