God
Who is God? Where does he come from? Are we created by him? These are questions that have baffled humans for centuries. Religious people believe we were created in the image and likeness of this creator. So this would mean that God is a human-like entity. And if he is human, is he not just as flawed as we are? In my personal opinion, this God who created us must be a higher form of human that has somehow found a way to control the course of our galaxy. Sounds a little science-fiction, but it may be true.
If God is a form of human then this would explain why the Earth is not perfect. There are wars, starvation, natural disasters and many other perils which threaten mankind. We could say that since the world is not this idyllic and peaceful place, God is only human. He is a form of human that is just as flawed and subjected to temptations as we are. A bit of a controversial theory, but still plausible nonetheless.
