Sforno on Exodus 6:2/ספורנו על שמות ו׳:ב׳

1'אני ה, the One Who maintains the entire universe all alone. I have not only called it into existence, but I also maintain it, and there is no other prime cause which exercises any independent influence on any part of My universe. Compare Nechemyah 9,6 ואתה מחיה את כולם “and You alone provide the nourishment to keep all creatures alive.” Unless I had given My consent no creature could continue to exist.
