As far as I understand it, Moses. All the civilizations and cultures prior to Moses were polytheistic, the egyptians etc. Anyone understand this better? Well I mean God spoke to Noah? but the cultures in that time in that area were all polytheistic.

Ethical monotheism was in the tradition of ancient Hebrew religion and is associated with the teachings of prophets like Moses and Elijah. It emphasized the belief in one ethical and moral God who expected righteousness and justice from his followers. This concept had a significant influence on the development of Judaism, Christianity, and Islam.

Abraham and Moses are considered prophets in the Abrahamic religions of Judaism, Christianity, and Islam. They are revered figures in all three faiths for their leadership, teachings, and guidance in spreading monotheism.

Scholars say that monotheistic Judaism was adopted by King Josiah in the seventh century BCE, seven hundred years after the time usually attributed to Moses. However, Zoroastrianism was already a monotheistic religion well before the fifteenth century BCE.

Monotheism is the belief of one god.
