The Universe Exist In The Being Of God, As The Being Of God Or Apart From It
Man has no means to know and determine the nature of God and whether the universe emanates from Him or not. God in the Quran told us that the universe is His creation and is a separate entity. The rest is speculation (Zann) and Zann works not against the reality told by God. To believe this information, we need to believe in Quran first and this has its own arguments.
