1) Allah didn't exist in written form before muhammed's time?
http://www.pantheon.org/articles/a/allah.html
This link says otherwise.
2) Where then is the muslim equivalent of the word Yahweh? If middle eastern Christians can do it, why not muslims? To this day, does ANYONE know what Yahweh translates into in arabic?
3) If that's the case then how do you explain allah's daughter's name "Allat" which literally means "The Goddess"? or his other daughter's name "Aluzzah" which means "The invincible"? allah means "the god". What muslims say now means nothing to me. It originally meant "the god", nothing more, nothing less.
4) Jesus didn't call out "Yahweh" because Jews (believing Jews) never used that word because it was considered so holy. Eloi means "my God", Jesus being Jewish was addressing it to Yahweh. When a Christian says "Thank God" we rigthly assume he's referring to the Judeo-Christian deity Yahweh. When a Hindu says "Thank God" we would rightly assume he's addressing a deity in his pantheon of Gods. God is not a proper name like : Jesus, Vishnu, Yahweh, Zeus, etc....
5) Find, show me how the word Yahweh is in any way connected with the word "allah".
The link does not actually say that. Although I find it interesting that the same site claims that Yahweh was a Canaanite rain god with a bull-horned helmet.

Where then is the muslim equivalent of the word Yahweh? What is the Muslim equivalent of Milwaukee? YHVH is that YHVH is. If any name is untranslatable, it is The Name. The Tetragrammatron can be represented in Arabic by four letters, just as it is represented by four letters in the Roman alphabet. Ya`-ha`-waw-ya` is much closer to yod-he-vav-he than Y-H-V-H is.
It originally meant "the god", nothing more, nothing less.
And "I am that I am" originally meant a affirmative statement of existence. God's revelation changed that.
More importantly, "al-ilah" is two words meaning "the god" and "Allah" is a single word meaning "God".
Eloi means "my God", Jesus being Jewish was addressing it to Yahweh.
Specifically, it means, "my El", referring to the Levantine sky god El, the husband of the goddess Ashera and the father of the gods Hadad, Yam, and Mot. According to the pantheon.org source you quoted, El is traditionally (as well as Biblically) associated with YHVH.

They are both Names of God in the Abrahamic tradition, and the names used in Jewish Hebrew and Muslim Arabic scriptures, respectively.
