how did ancient israelites distinguish god's work in the cosmos from that of other cultures?

The passage, plainly, with room to sit with it.

Isaiah 44:6

“Thus says Yahweh, the King of Israel, and his Redeemer, Yahweh of Armies: 'I am the first, and I am the last; and besides me there is no God.'”

The prophet Isaiah, writing to the people of Judah during a time of significant political turmoil and exile (8th-6th centuries BCE), frequently reminds them of God's unmatched power and singular identity. This particular verse emphasizes God's unique claim as the one true divine being.

How does recognizing an ultimate, singular source of all things shape one's understanding of the world's order and meaning?
