I would like to make objects spawn and aim for a object that i have to dodge

Here's something to get you started. You may want to change it so that it aims a bit above the target to compensate for gravity.

 public class DodgeBallCreator : MonoBehaviour {
     public GameObject goTarget; // Where to target
     
     void Start() {
     InvokeRepeating ("ThrowBall", 0.0f, 2.0f);
     }
 
     void ThrowBall() {
         GameObject go = GameObject.CreatePrimitive(PrimitiveType.Sphere);
         go.transform.position = transform.position;
         go.AddComponent<Rigidbody>();
         go.transform.LookAt(goTarget.transform.position);
         go.rigidbody.AddRelativeForce(Vector3.forward*1000);
     }
 }
