Kingdom of Israel/Kingdom of Judah (Late Bronze-Early Iron Age-1047-BCE-587 BCE) Religion: Yahwism-Polytheistic, Ancient Semitic Religion-Polytheistic
Second Temple Period (587 BCE - 1st Century CE): Religion: Judaism-Monotheism
1600 BCE - 587 BCE = 1013 years. That's a quick process to you? Even the range from the late Bronze Age to the period of when Judaism was officially born isn't exactly a short time frame.
