by definition God (if the biblical definition is used). God would have to be outside of creation, the things made, like the universe. God would have to be something more powerful than the universe & the laws of physics in order to create them, for example, cause & effect, the cause has to be greater than the effect.
scientists tell us time was created at the beginning of the universe. God is outside of time. the universe is stuck in time since it had a beginning & it has a ending event.
by definition, there is God then everything else, creation.
'In the beginning God created the heavens & the earth.'
genesis 1:1
'...before you had formed the earth & the world,
from eternity past to eternity future you are God.'
psalms 90:2
