It's still that way. I guess later some letters started indicating certain vowel sounds a bit more directly, but it's mostly little dots and lines that only get used to teach or are placed on text where ambiguity isn't acceptable.
Explains a whole lot of this reality, its gueys all the way down to lowest hells and all the way up to the highest heavens. I look in the mirror I see a guey staring back at me, and all around me is guey.

In the early days, Yahweh was conceptualized as a jealous god among a pantheon. He was not the only god, just the aligned god of certain groups, contrasted to the competitors like Baal and preceded by those like El (later Elohim). Yahweh transformed over time from the favored and representative god of one group to being the correct and highest and then only god, becoming conflated with El much later.
The idea that such a being would care even a whit about human existence is the height of arrogance. Spirituality I can understand as a personal predilection, but religion... religion is narcissists demanding that the universe acknowledge them.
