How to get the position of an Instantiated Object from an other script ?

I use Photon Network to Instantiate an object in the scene, but then I want to save it’s position in an other script.
try
{
//Load Player
PlayerData data = SaveSystem.LoadPlayer();

            Vector3 position;
            position.x = data.position[0];
            position.y = data.position[1] + 2f;
            position.z = data.position[2];

            Debug.Log(position.ToString());

            GameObject player = PhotonNetwork.Instantiate(playerPrefab.name, position, Quaternion.identity);
            Debug.Log("Instantiated new Player from save file");
        }
        catch (System.Exception)
        {
            Debug.LogError("Couldn't find any save file, creating one");
            Vector3 randomPosition = new Vector3(Random.Range(minX, maxX), 3, Random.Range(minZ, maxZ));
            GameObject player = PhotonNetwork.Instantiate(playerPrefab.name, randomPosition, Quaternion.identity);
            throw;
        }

But the problem is that I can’t get the variable “player” elsewhere, I get an error saying that :

The name 'player' does not exist in the current context [Assembly-CSharp]

The other way I tried saving the position is by using the PlayerPrefab’s position, but it never changes, and so doesn’t match the player’s real-time position

I found out whats was wrong : I needed to make my variables “static”
