First of all, let's say that in order for something to exist there must be a creator. A book exists because someone wrote it, a house exists because someone built it--let's assume that this principle applies to the entire universe. Let us also say that these creations exist in respect to the thoughts of the creator. There is an undeniable relationship between the creation and the creator--by reading a book you can understand the thoughts of the author, and by looking at a house you can understand the thoughts of the architect. These creations mimic--if you will--the mind of the creator. Therefore, because human thought is very fallible and makes constant mistakes these creations--that is creations spawned from human thought--can never be perfect. Using these previous assumptions we begin with the problem of the Universe. The Universe--as far as we can tell--exists, therefore, there is a creator. Let's call this creator--out of ease--God. God, as many people believe, is perfect. Therefore, using this same principle of logic we can say that his mind is perfect--because his actions are in result of his mind. So in order to have perfect actions you must contain a perfect mind. God created the Universe, therefore the Universe should mimic--as we've seen with other examples--the thoughts of God--which, as I just stated, are perfect. This would mean that the Universe is perfect. Well, as we all know, the Universe is far from perfect. This is where our proof breaks down. The Universe is not perfect, yet it is still mimicing the thought of it's creator--in other words it is still mimicing the thought of God. Then that means that God's mind is not perfect--and therefore God is not perfect. This means that God--whatever this mystical and unknown force is--is fallible. Although, due to the hugeness of the Universe this would also mean that God's mind is far more powerful than that of any human beings--because no human being could ever create anything as huge and extensive as the Universe. Therefore, God has a very powerful and very fallible mind--but is in no means perfect.
Let's also look at how things are created on Earth. And not small things but more importantly larger more complex things such as cars, machines and buildings. Each of these objects are created not by one person but by hundreds and maybe thousands. Teams of humans are put to work in order to complete complex projects. Let's also look at how children--possibly the most complex creation of human beings--are born. Human beings are not asexual, there must be a mother and a father in order to produce a child. So, there is an underlying principle on Earth, and this principle is: nothing complex can be created by one person. This totally contradicts the common belief that one man--God--created the universe. Although, most of these statements are followed--or preceeded--by the statement that God is perfect, which I just dissproved above. God is not perfect--therefore, he could not create anything so complex as the Universe by himself. He would need the help of hundreds of "gods" in order to complete this task. To say that God created the universe in seven days is total blashpemy. One person cannot complete a complex project on their own in a short period of time. This is why we have companies and other organizational structures in society so that we can complete complex projects in a reasonable amount of time. If we relate the Universe to a child then God had a wife, and the Universe spawned from the womb of this wonderful woman. If we ignore this analogy of the Universe being a child then there had to have been hundreds of workers completing the Universe--not just one. Basically, the concept that God--one "person"--created the Universe is horribly, horribly wrong.
