Of course! Creation cannot exists without creator.
God is the Only creator of this universe. If he will mot have to exists then nothing will be here at first place.
Creation can't come into existence without creator. There is not a single case where anything has come into existence at its own.
The very idea of God is clear, we say God in everything from the nature to life to death.
If considered, anything can be ignored but we do have brain to use as much as needed. So, when we go deep into the thought, it comes clear that God's existence is fact.
