Why are we here? - God is imperfect.

God
The Being perfect in power, wisdom, and goodness who is worshiped as creator and ruler of the universe.
Perfect
Being entirely without fault or defect.
Complete
Having all necessary parts, elements, or steps.
Just
Acting or being in conformity with what is morally upright or good.

When I was younger, I was taught that God, the god of the Bible, was complete, perfect, and just. That He was omniscient, omnipresent, and omnipotent.

So, why are we here?

If God is perfect and complete then He is self-sufficient. He is in need of nothing. There is nothing that He needs to complete Himself. He does not need food or shelter or companionship. To add anything to a perfect “anything” makes it imperfect. So if God doesn’t need us, He must want us. But “wanting” is a form of need. It is not a physical need, but it is a need nonetheless. It is a psychology need. I want something because it fulfils some sort of emotional need. If only I could have ‘x’, then I would be happy. Would a god have emotional needs? Not a perfect god. “Wants”, i.e., “emotional needs” indicate a defect, a sense of dissatisfaction to some degree. But, how could a perfect being be dissatisfied? Being perfect would imply being psychologically perfect as well. Such a being should be contented with existence as it is.

There should be no need or desire in a perfect god. So why are we here? I submit that if, for the sake of discussion, we assume that God exists, then we are here because God either needed us or wanted us. In either case, this would mean that God is imperfect. But if He is imperfect, then he is not a god.
