for me, I believe in a god.
not THE God
but A god.
I believe that though science can explain everything being created (big bang, evolution, etc) some unknown god has created the base materials and formula for the events of the universe, the molecules and/or DNA of existance, if you will. I believe this because people have senses of what is right and wrong, and because existance had to start somewhere. I also feel that the fact that many humans feel a need to believe or even disbelieve in god(s) is proof of a holy existance. I, however, feel that there can be no proof of the number of gods, goddesses, and/or spirits, let alone sex, appearance, species, location, heaven, hell, reincarnation, or form of said deities.
I also feel that there is no "right" or "true" religion. I feel that one can learn many different things from many different religions, that everyone can contribute. I feel there should be no dogma, but one should simply believe whatever one wishes to. I personally feel that all are equal, no matter who they are, every life is equal.
After googling my beliefs and taking a religion test, I found my beliefs closest to those of Unitarian Universalists (read more on wikipedia:

So yes, I feel god(s) exist around/in/above us/somewhere/somehow. But I'm not sure who/what/where they/he/she/it are/is.
Existance itself, in its beauties, faults, conformities and anomalies, I believe, prooves this.
