A number of scholars opine that AmenHoteb/p IV was the first Egyptian Monarch who was a Monothiest and a founder of Egyptian Monothiesm. But this opinion is incorrect. Since Monothiesm did exist in Ancient Egypt. Although majority of Egyptian were Polythiests and followed a Polythiestic religion may be renamed as Egyptian Polythiestic Religion, there were two more religions beside this one,a] Monothiestic Religion, b]Harmonic Religion.

Egyptian Monothiestic Religion believed in only one God.Harmonic religion believed that there is only one God , and all the lower gods and godesses are just the incarnations or manifestations of this God.

But these two religions were in minority in ancient Egypt. Dr Burgsche has provided sufficient evidence on the existence of Monothiestic Egyptian in ancient Egypt.

Some articles of faith of Egyptian Monothiestic Creed:-

a)God is with out a proper name.How ever He hath numerous names/epithets.

b)God Is One and Alone

c)God hath made All Things.

d)He Hath been from the Begining. He Hath Been from the Old.

e)He Existed when nothing else Existed.

f)God Is Truth and He liveth by Truth.

e) God is Eternal and Infinite.

f)No man knoweth His Likeness.

g) No man knoweth how to know Him.

2] La croyance a Uni du Dieu Supreme.

If this is all correct then it is clear that Amen Hoteb/p IV was not the first person who was a Monothiest in ancient Egypt but this religion Pre-Existed him.

How ever like Hitler who made his own reforms in the game of Cricket , this Egyptian Monarch modified Monothiestic Religion of Ancient Egypt according to his mentality and sensiblity. Such modifications cannot prove that Monothiestic Ideas came in his mind out of nothing , and from no where.

Instead he borrowed them from Ancient Egyptian Religion and modified to some extent.

AkhenAten tried to equate the the nameless God of Monothistic Egyptian Religion by a god named Aten in Polytiestic Religion of Egypt.

So ancient Monothiestic Religion of Egypt was merged with AkhenAten's Monothiestic religion. Yet it cannot be said that the followers of the ancient ceased them must have become much less in number.

After AkhenAten however all Monothiestic religions in Egypt must have declined , and did cease to be even as a minority religions, wwith the possible exception of some individuals holding some sort of Monothiestic religion.
