Final answer:
The ancient Israelites' beliefs, as recorded in the Hebrew Bible, have survived to form one of the world's oldest monotheistic religions, Judaism, which influenced Christianity and Islam and had a significant impact on Western Civilization.
Step-by-step explanation:
Through writing the Hebrew Bible the beliefs of the ancient Israelites survive to become one of the world's oldest monotheistic religions. The monotheism of the ancient Hebrews, embodied in their worship of Yahweh, evolved over time from henotheism, a belief in many gods but the worship of only one, to true monotheism—the belief in the existence of a single deity.
This transition is chronicled in their sacred texts which form part of the Tanakh or Hebrew Bible in Judaism and the Old Testament in Christianity, also laying the religious groundwork for Islam and influencing Western Civilization profoundly. The Hebrew culture was unique in its worship of one God, an idea introduced by Abraham and shaped further by prophets like Moses.
Despite the challenges of historical reconstruction due to oral transmission before these texts were written, Judaism's foundational beliefs have continued to have a significant impact on global religious and cultural development to this very day.
