Akhenaton's monotheism was political/dynastic and meant to enable family power. The pharaohs became gods and worship exclusive. In the following millennium, the Assyrians had a martial god which they followed mainly and nationally rather than exclusively. This development I see as more likely to have inspired monotheism. It inspired the national god of the Hebrews, and was exclusive to them and the kings.

Dominic Perry, in his history of Egypt podcast, does an excellent job of pointing out that Akhenaten wasn't truly a monotheist. He was a religious reformer, and he did focus extensively on Aten, but he didn't completely get rid of the other gods. There were still shrines and temples to the other gods active throughout Egypt during his reign. The Lesser deities he seemed to keep pretty much intact as far as any type of worship went. The ones that drew his attention the most were those that would be competition for Aten, other main deities like Ra. Those are the gods Akhenaten downplayed and pushed aside, but he still didn't get rid of the Egyptian pantheon. In popular and pseudoarcheology, Akhenaten is often linked with figures such as Moses. To solidify any such comparison we would need much more evidence than we have now. Proposed dates for any type of event that might be the basis of The Exodus range from the mid 15th century BCE to to the cusp of the late bronze age collapse. Akhenaten's reign falls between these two poles, but without dates for an actual event of any type, we can't compare Akhenaten to any figure such as Moses with any kind to certainty.

"Above all, though Akhenaten is known for his development of a kind of early monotheism that stressed the uniqueness of the sun god Aten, and of Akhenaten’s own relationship with this god. For this king, there was only one god and only one person who now knew the god: Akhenaten himself."

In the book of Exodus, the phoroahs were stereotypes of worshipping gods instead of Jehovah. This king may be an exception, who stressed the uniqueness of he sun god Aten.

In Mesopotamia, around 3500 BC the Sumerian population began to grow. Villages appeared. The Sumerians had about 1000 gods and goddesses. Many Gods of Nature (mountains, trees, rivers, stones, wind, sky, earth, sun, moon, fire, rain, thunder, lightning, sun, moon etc…). In this plethora of gods, a family chose one of those gods of whom they kept a statue and whom they adored exclusively. Other families had other idols. The village grew and after a while became a city with a king who himself chose a god to his liking who became the god of the city without forcing the population to do the same. But this god did not replace that of the family. One can regard this fervor for a special god as a form of monotheism?
