If you had made that "nothing" with a capital letter I could have taken as another name for God. You are right again. Time did not exist because time is part of the universe as an accident of motion. The motion of matter.
"Not even God!" When Moses needed a name of reference to answer questions about Who had sent him to free the Jewish People from slavery in Egypt the name given was "I AM". Tell them that I AM sent you. God is before the universe was caused into existence and still is. He does not operate within the frame of time and space. I understand you cannot walk in that realm of perception. Your mind cannot conceive the esoteric attribute of Metaphysics. If God had had a beginning He could not be God. We would have either to quit on Him or go for something else to explain how the universe came about if it could not cause itself into existence. Could you? How could you! The only thing you know is that there is no God, that's all.
