When we talk of God, we are talking about the creator of this universe, all the other gods who did not create this world are not what we are discussing here

John Lennox studied about ancient gods, he clearly explained how all those ancient gods such as greek gods, roman gods, hindu gods have theogony, which means they all have a creation story. The God we are talking about has no creation story, for this God is eternal. The ancient gods descended down from the heavens, God the creator created the heavens, this is the difference, and it is major one.
