I cannot imagine how the clockwork of the universe can exist without a clockmaker.

Voltaire 

I don't understand how people don't/won't believe in God. How can this world work correctly if there isn't someone making sure that it is? It's like saying a car will run smoothly if we never take it to a mechanic; the car wouldn't even exist in the first place if someone didn't make it. Just like everything else, someone had to make this world. Something isn't made out of nothing.
