I believe in higher power or higher dimensional beings. Somewhere out of our "system".
Dimensional as in... Imagine:
If you were a 2 dimensional being on a piece of paper and that's all you know. You will not be able to see height. You would run around every day with your 2D friends with lines as walls around your house and such. But a 3D being will be able to look down and see right through your house, car, your world, and even your body. That 3D being will be able to make something appear as if by magic because all he/she would have to do is set something down. But you have no concept of this "down" so you believe that god just sent you a present. This god will be able to create new worlds for you, be able to teleport you to places by picking you "up" then droping you "down" elsewhere. This god will be able to do unimaginable things.
But we are not able to imagin those things that higher dimensional beings are able to do. We are limited by our own "system". It might be easier for people to think of the other posibilities if they were to think smaller... such as 2D.
