I guess you never thought about it, did you?

[Little Rik]

Most atheists come to the conclusion that God doesn't exist on the ground that God doesn't show to them in any way.

Put the question in this way.
Suppose is all a game for God.
God like to create something very small and through evolution this small become big.
A bit like you when you see your baby become a man like you.
How can you explain a baby how the system works?
He-she could not even understand anything beside if you allow the baby to grow to man without going trough the evolution stages what would be the point in creating the universe?

If God would tell you where is hidden the gold's nugget then the game wouldn't make any sense.

Smart people understand how the game works and play according to the rules in order to get at the nugget ASAP while idiots don't and waste their precious time whining and swearing with no end in sight so the goal of life become more and more distant.  

Suppose god is an unintelligent space slug who created the universe accidentally by taking a poop made of enough antimatter to unravel and re-start the universe. What then, Rik? You ever think of that?

An unintelligent space slug can not possibly create a huge and complex universe with intelligent life in it.
(Don't get excited Pinky, I didn't say that you are intelligent )

Have you ever seen a donkey give birth to a human being?
So a slug will give birth to a similar slug not to a human being.    

Failed analogy mate.

In a physical sense it would be like when you go from Berlin to Paris in train.
You can't be wrong.
You feel that Paris is closer and closer. (example)

Just to be clear do you think you can feel Paris getting closer?

If someone bound you gagged you and dump you in a freight wagons it will be very hard to know where you are going but if you on your free will decide to travel to Paris then is obvious that you feel your goal within.
