Being Creator Makes God God
nIsaiah 45:5-12
n5 I am the Lord, and there is none else, there is no God beside me:  I girded thee, though thou hast not known me:
n6 That they may know from the rising of the sun, and from the west, that there is none beside me.  I am the Lord, and there is none else.
n7 I form the light, and create darkness:  I make peace, and create calamity;  I the Lord do all these things.
n8 Drop down, ye heavens, from above, and  let the skies pour down righteousness;  let the earth open, and let them bring forth salvation, and let righteousness spring up together;  I the Lord have created it.
n12 I have made the earth, and created man upon it:  I, even my hands, have stretched out the heavens, and all their host have I commanded.
Note that this is when God was talking to Cyrus.  He is basically saying this is why you had better listen up and do what I have for you to do.
