1- If you say that everything was created by Allah (God), then who created Allah?

2 - Why does Allah not show Himself?

3- If you say that Allah is omnipotent (all powerful, can do everything), then can He make a rock so big that He can't even lift?

4- Can Allah make another Allah exactly as Himself?

5- Why only one Eternal and Everlasting as you mentioned in this thread?

6- Why Allah? Why not flying spaghetti monster or invisible flying pink unicorn?
