I am making a 2d runner game in godot 3.5 and shooting is a component of it

Everything works fine, but there is a technical problem with the bullet positioning. I am relatively new in coding in general too, so best believe i’ve tried all ways of dealing with it.

When I click tab button, the bullets stack up on top as shown. I want it to shoot from the player’s position. I don’t know how to fix this. Any suggestions would be appreciated.

Player:

const UP = Vector2(0, -1)
const SPEED = 200
const GRAVITY = 20
const JUMP_HEIGHT = -690
var motion = Vector2() # moving in 2d space

func _physics_process(_delta):
    motion.y += GRAVITY

    if Input.is_action_pressed("ui_right"):
        $Sprite.flip_h = false # Do not flip the sprite
        motion.x = SPEED
    elif Input.is_action_pressed("ui_left"):
        $Sprite.flip_h = true # Flip the sprite to face left
        motion.x = -SPEED
    else:
        motion.x = 0

    # Play appropriate animation based on character's movement
    if motion.x != 0: # If character is moving
        $Sprite.play("Run")
    else:
        $Sprite.play("Idle") # Match the play actions to the names of the animation states

    if is_on_floor():
        if Input.is_action_pressed("ui_up"):
            motion.y = JUMP_HEIGHT
    else:
        if motion.y < 0:
            $Sprite.play("Jump")
            print("jump")
        else:
            $Sprite.play("Fall")
            print("fall")

    # use move_and_slide to create movement on screen
    motion = move_and_slide(motion, UP)


# bullets

const SHOOT_SPEED = 300
var bulletscene = preload("res://Shoot.tscn")

func _process(delta):
    if Input.is_action_just_pressed("ui_accept"):
        shoot()

    $Node2D.look_at(get_global_mouse_position())

func shoot():
    var bullet = bulletscene.instance()

    get_parent().add_child(bullet)
    bullet.position = $Node2D/Position2D.position

    bullet.velocity = get_global_mouse_position() - bullet.position
