GOD, by definition, is the only Sovereign, Self-Existing, non-created Being to whom everything else owes its existence and completely depends on for survival and power.
He needs nothing to exist, to give Him power, or to make Him complete. He is entirely Self-Sufficient, Independent, and Perfect.
If He was created, limited, changeable, needy, or imperfect in any way, He would lose one of His essential divine attributes and would no longer be God.
He has always existed and will always exist.
He is not bound by time, space, or the laws of nature, since He cannot be subject to what He created. Rather, He is beyond them, just as a craftsman is beyond the dimensions of his own creation.
There are traces of past and present creations everywhere — are they meaningless or living signs of a Creator God?Soucre Link
