The etymology of some words have previous origins, but that's it.
What are you basing this on? It's pretty settled among historians that the Abrahamic God is Yahweh, who was previously a minor deity in the Canaanite pantheon.

The concept of God in...all of Abrahamic monotheism...is very different from other religions (including the pagan religions of the time), it's way less bestial and/or anthropomorphic and local.
Whoa. Super judgemental here, and also wrong.
Semitic polytheism transitioned into Abrahamic monotheism by way of Yahwism, a variety of Canaanite paganism centred on Yahweh, the national god of the Iron Age kingdoms of Israel and Judah. In this process, Yahweh was syncretized with El, the supreme god of the Canaanite pantheon, whose name "El" אל, or elah אלה is a word for "god" in Hebrew, cognate to Arabic ʼilāh إله, and its definitive pronoun form الله Allāh, "(The) God".
