I suppose people interject religion and faith as if they are one and the same. Deistic beliefs are still religious, but they are based on reason and logic, and are not based on faith or mysticism. There are no dogmatic texts, no interventionist being to worship, just what reason reveals to us in our observable existence.
I akin it to if you were a computer AI inside a fictitious synthetic world. There are rules governing the synthetic universe. Obviously these weren't organically formed, and it stands to reason any set of laws who you cannot break would have been created. Everything we know leads us to this logic and observable fact. Do I know absolutely that the Universe was created? Not for certain, but again, it is the best explanation there is, and until a better one is put forth I will believe in this. I think science is heading in a very deistic direction. They are mutual partners. Again, most people who believe in a Universe that was created and not just always here, don't see it as an act of 'God' in the abstract (Where I do). It is up to personal interpretation, but what we know so far points us to believe that indeed, the Universe was created, and has not merely 'always been'.
I certainly don't believe in the Christian creationist theoram. In fact, it is pretty well easy to dismantle that. However, creation & evolution do go hand in hand pretty well, and well again, it is up to personal interpration if you wish to call the Universe 'God' or not.
