just another god hypothetical ...

Also, science can not measure outside space and time, therefore, science can not come to any conclusion that a supreme entity does not exist.  Also the supreme entity "God" that I am referring to is perhaps superior to the entity you suggested in your post and perhaps your suggested entity in the post may  be worshiping a supreme entity that I am referring to.   And this supreme entity perhaps has the energy that is needed to sustain life, both ours and the one you posted about.   And this energy is not detectable.  

Science (more Technology) is helpful but limited too.

I think what you are missing here is the realm beyond what we can grasp in our current physical state.  To assume nothing exists beyond ourselves and what we observe or measure is short sighted.

To assert that something exists which cannot be established is foolish.
