Why we cannot see God

SharingForToday#5 : If God really exist, why we cannot see God? (in Islam)

An analogy; I create a pen. I am the creator, and the pen is the creation.
Can I see the pen?
Sure, I can, I am the creator of it.
Can the pen see its creator, me?
No.
If the pen cannot see me, am I not exist?
.....
Then why the pen cannot see me?
Because I didn't provide it the sense (pancaindera) for it to see me.
Why?
I'm the creator, my wish la!
