God has satelite?

This conversation happened almost a year ago.

One day, my son's nursery feedback that he has been skipping his nap for quite a long time. He is not doing anything but just lying on the bed for more than an hour, with his eyes open & shut. His teacher says, there is nothing wrong if he can't sleep. As long as he is taking a rest & most importantly, he isn't disturbing anyone.

As usual, I can't be any happier with this remark. I want him to take a real rest. Not just lying with his mind spinning. I pulled him aside after dinner & try to understand why, again.

"I do sleep."
"I know, very rarely you fall asleep. What keeps you busy even during your nap time? All of your friends are sleeping. There is no one to play with you."
"but I do sleep. Why teacher says I don't."
"well, your teachers have been checking all the time. They can't be wrong."
<< silent>>

"look, maybe we can deceit others but not God." "He sees everything than human is doing"
*I'm not sure why I loop in God in our conversation. Maybe seeking for support, even virtual.

"who is God?" I really put my foot in my mouth.
"well, the al-mighty that stays above us"
"what is al-mighty?"
"a very very big one, biggest ever than anything in the universe"
"very big one that stays in the air?"
"hmm.....ya. Big one that stays out of the earth but He can sees everything that happened on earth. Including every single thing that man is doing"
"wow......" seems he absorbed my explanation pretty fast.
"but..."
"what?" I'm trying my best to think of a new topic.
"since He is staying so far away, how can He sees everything on earth?"
"erm, let me think how to explain to you" >.<

"ah ah, I know mummy"
"God is using satelite la. That's why He can sees what is everyone doing"
"ya ya. Satelite." @.@|||
