Genesis 1:1 emphasizes the idea of a real beginning by putting it first in the sentence. None of the ancient religions had the idea of a real beginning. That means that God is the Creator of the entire heavens and the earth.
Not until modern science was the idea of a real beginning confirmed by anything outside of the Bible.
The beginning calls for a Beginner. Most ancient religions had different gods bringing different parts of the universe including different parts of the earth into being.
But the Old Testament makes it clear that there was only one God who began everything.
All through the Bible God is addressed as the Creator of the heavens and the earth (Isaiah 42:5) He has ultimate control of everything.
He gave us free will because he wanted us to be more than puppets. He wanted us to love Him as He loves us.
His creative powers raised Jesus from the dead. That gives us a sure hope of the future. God will be Victor and if we believe in Jesus we will share in His victory.
