Supernatural vs a Natural Uncaused Caused and Occam Razor

I just read something that I have been thinking about and it deals with a naturalistic view versus a super-naturalistic view of the cause of the universe and Occam Razor. Occam Razor simply means when you have two competing ideas that equally explains an observation go with the one that requires less explanation or the shorter explanation. In both ideas it is believed that the universe has a self-contained uncaused cause; in the naturalistic concept the universe itself is the self-contained uncaused cause while the super-naturalistic concept is a god is the self-contained uncaused cause of the universe, and thus Occam Razor would mean the naturalistic view should be accepted because it is the shorter explanation because of the one additional explanation of god for the theistic view. In other words, naturalism advocates the universe is itself the self-contained uncaused cause; while super-naturalism advocates that a supreme being is the self-contained uncaused cause. Now you have added something that requires an additional explanation: what is a supreme being?, who is the supreme being?, what evidence does god give for this supreme being’s existence? (I refuse to use a gender for god.) In all honesty both view may be false, we simply don‘t know, however I digress one of them is true because if a third alternative is given it would either be natural or supernatural. I too believe that there is an uncaused cause, because you would have to get to a point where there is something that was uncaused or you would have an infinite regression which is meaningless, because you would never explain anything, however using Occam Razor one would lean towards the universe itself being the self-contained uncaused cause because it requires one less step for explanation., therefore I accept the naturalistic point of view.
