It is often assumed that if there is a God that he is perfect, faultless, all good and all powerful. So when a nice young man happened to come across him whilst taking a walk he asked: ‘God why do you allow cancerous disease in the world.’ To which God replied
‘I do not allow it. I simply do not have the power to stop it. It is either a fault in my design to which I do not yet have the knowledge to correct or it is an inevitable by-product of the process of human creation just as carbon dioxide and other gases are unavoidable by-products of various chemical reactions. These gases are often detrimental or have no effect. But no one assumes that they serve such purposes, only that they have that function. Don’t be so hard on me. I am limited by my knowledge and the stretch of my innate faculties just as you are. You know, you have very high standards of me. You put me up on a pedestal that is really just too hard to stand on. I am not all powerful you know. Heck! Why would I be? You’re not. Please stop worshipping me. I’m as flawed as the next being, I just happen to be a bit more intelligent than you.’
We assume God is perfect because we created him to be so. God is our answer to material problems to which we cannot see the material solutions. So he has to be perfect or else he can’t solve all the problems we want him to solve. And if he can’t do that then we might just as well have not made him up.

Here's one answer:
If you accept that there is perfection in the universe i.e., logic, maths, geometry and the laws of physics then one would have to accept that God (if he exists) was also perfect, as the creator of these laws.
Science is based on the idea that the Universe is knowable, consistant and understandable. The pursuit of science is based upon this principle, so in a sense, the universe is perfect. This being the case, God is also perfect.
Whether God can be proven to exist is not really the point, it is a world view held by many that God is the cause (and in a way the purpose) of the Universe.
You are familiar with the situation where one person bumps into an old friend and says "What are you doing here?" The facecious reply is often "Talking to you", or "My legs carried me." It is funny because it is not really answering the question.
I am at work. Previous to this I was in a cafe eating food. Prior to that I was walking across town, over a bridge. Before I had left my house I had a shower and got changed. This chain of events was triggered by my alarm clock going off. A scientist, with no other knowledge, observing from affar could then answer the question "Why Am I at work?" with "Because of his alarm clock 60 minutes before." What he would be describing is the chain of events leading to my arriving at work, but without describing WHY my alarm clock went off in the first place.
The God hypothesis was created in order to answer the question of the meaning or purpose behind our existence. The answer to the question "Why are we here" is not "Gravity and Electromagnetism" then... we do not know the answer. Some people choose to believe in a Creator, others not. As I said in the beginning, it is a world view. Science does not disproove God as that is something science cannot do, like measure beauty or goodness.
You have chosen to believe that there is no God - so the answer to the question "Why are we here" is either "I don't know" or "No reason at all." Some people don't like either of those.
If God IS the answer, then he must have the following properties:
Existence
Perfection
Eternal
What is included as being 'perfect' is also up for debate, we know that Descartes tried making out that perfection must mean that he exists, so therefore he exists, but I think he had got bored at that point.
As for the issue of an afterlife, interaction with the Creator, a continuous manipulation by the Creator (miracles, answering prayers etc) and a moral code... well that's another story.
