God vs. Ghosts

Sometimes I find that my beliefs contradict themselves, because although I don't believe in god, I do believe in ghosts and spirits. Are gods and ghosts in the same category? Can one believe in one without the other? Both are in the supernatural category. Both are used to explain events that are otherwise uexplainable. Both are either strongly supported or not believed in at all. I have never had an exerience that proved to me the existence of an all-powerful god, nor do I choose to believe in "miracles". I do, however, believe in ghosts and spirits because I have had experiences with such beings. Yes, it could be possible that I am simply using the idea of ghosts to exlain things that I do not understand, but it is also possible that what I saw and heard was real. Without proof I am extremely cynical, and I have proof in my own mind that ghosts exist. God, on the other hand, has no bearing in my life and the very thought of an all-powerful being is laughable to me. That does not mean I do not respect the beliefs of others, it is simply my choice. I expect that others will laugh at my belief in ghosts and other phenomena, but I have accepted that. So the question remains: Are ghosts and god the same thing? If you really think about it, it seems silly to believe in one and not the other. Before I had several experiences with "ghosts", I did not believe in them. Physical proof is needed to get past my stubborn and cynical barrier, and I got the proof I needed. But I digress.
Ghosts and god are in the same category, but there are differences. There have been theories put forward that ghosts are simply imprints of energy from the past. God, however, is something that faith alone can prove. Yes, there are some so-called "miracles", but I am sure most of them could be explained by science, and in some cases even common sense. However, I will not rule out the possibility that a supernatural force may have something to do with it, although I do not believe that it is a god. The majority of the human brain is still a mystery to us, so maybe humans are the ones who are creating these "miracles". People have their own reasons for believing in things. Maybe I need to believe in ghosts for some reason, or maybe they are real. Maybe there is a god, even though I do not believe in it. Many people receive comfort from their own beliefs, so I suppose it does not matter whether ghosts and gods are real, as long as people are happy with their beliefs.
