Theres a famous argument about a cat in a box and how you only know if the cat is dead when you look inside the box. Now it then follows that is a sky daddy existed they would be able to look in the box when you arent and so if a sky daddy existed the cat would die when you look in the box. But ofcourse, the cat dies when you look in the box, or your sky daddy, and so you are more important in nature than your sky daddy. But why would a sky daddy make such a world? Obviously they dont exist as otherwise the cat would die before you look inside the box when ti doesnt.
This type of argument is the sort the most intellectualy sophistated philosophers use. I admit that it seems a difficult argument to understand, and if I struggle to understand it I imagine it will go over the heads of you xians.
