Monotheism has been knocking around for quite a long time. Back around 1350 BC in Egypt Amenhotep IV (meaning Amun is Satisfied) departed from traditional religion and renamed himself Akhenaten (Living spirit of Aten).
The prayer below is clipped from the Great Hymn to Aten. Reading it I am struck by how easily the name Aten can be substituted for Jaweh, Jehovah, God, Allah, Ahura Mazda or the Flying Spaghetti Monster.

“The Great Hymn to [Insert Desired Deity Name]”
How manifold it is, what you have made!
Your workings hidden from the face of man.
O sole god, like whom there is no other!
You created the world according to your desire,
While you were alone: All men, cattle, and wild beasts,
Whatever is on earth, going upon its feet,
And what is on high, flying with its wings.
The countries of Syria and Nubia, the land of Egypt,
You set every man in his place,
You supply their necessities:
Everyone has his food, and his time of life is reckoned.
Their tongues are separate in speech,
And their natures as well;
Their skins are distinguished,
As You distinguish the foreign peoples.
You make us a world in the afterlife,
You bring forth as You desire
To maintain Your people
According as You made them for Yourself,
The Lord of all of them, caring for them,
The Lord of every land, ruling them,
The [insert desired deity name] of the day, great of majesty.
