Why do you think god and human nature are so closely related?

In the Bible, god gets jealous, angry, sad, and makes up all kinds of rules. He created 10 commandments (why not 11?), sounds alot like humans personified God. hmmmm I wonder. I would think god would be beyond such trivial human emotions. I wonder if he gets hungry as well. I believe in God, but I think he can not be packaged or understood
