So God has two hands? With 5 fingers each? Is there skin on those fingers? Muscles and tendons in those hands? A circulation to nourish the skin and muscles? A nervous system to stimulate the muscles? A brain to exert conscious will over the nervous system? And all of this "outside" of the universe?
Asimov is right. Your mind is stuck in ancient Middle Eastern mythology.

Scientists demand "proof" of everything -- except regarding the issues of a supposed BB creation of the Universe and a tall tale of evolution taught for years as "fact" that requires such a leap of faith that defies ANYt scientific "probabiliy." Yet somehow then "proof" isn't important in the least, and "assumptions" conveniently become a more than adequate substitute.
While science cannot accept the existance of an extraneous dimension of time, space, and spirit of which is completely impervious to the universal physical or material law, it does indeed exist.
