The question that makes fundies hostile

[Mystical]

to be honest with you I know nothing of Yahweh or Allah's origins. I was under the impression (when i was a believer) that the Muslims were disinherited by Abraham when he banished his son Ishmael and the maid servant Hagar to the desert (even though Ishmael was by all rights first offspring and confirmed into the clan via circumsicion )and that's why they made up a document claiming their right to inheritence of something (forgive my ignorance, I just didnt care). Mohammad became their Jesus in effect, a messenger of god. and they don't believe Jesus is the son of god but a prophet.

As for Yahweh I found this written by a pastor.
Is it in line with what you believe to be true?

The Protoindo European god Yayash, Yaë or Yave, a protective god whose symbol was a tree, signifying possibly '"walking", "going", "a pilgrim", has been dated back to the Indus River valley, circa 2900 B.C.E. He has been identified with the Turko Syrian Yahveh, a "sacred animal or organization".

"Yahweh appears to have been originally a sky god - a god of thunder and lightning. He was associated with mountains and was called by the enemies of Israel 'a god of the hills'. His manifestation was often as fire, as at Mount Sinai and in the burning bush." "A shorter form, 'Yah', was also used (Exodus 15:2) and some scholars believe that this is the older form, originating in an exclamation to God -'Yah!' - which came to be accepted as the divine name. Others claim that it is from the root 'hayah', 'to be' or 'to become', and that it meant 'I am that I am' or I will be that I will be'. According to one tradition of the call of Moses, the divine name Yahweh was revealed to him in Egypt: - Great Events of Bible Times

"Originally, these four consonants [in YHWH] represented the four members of the Heavenly Family: Y represented El the Father; H was Asherah the Mother; W corresponded to He the Son; and H was the Daughter Anath. In accordance with the royal traditions of the time and region, God's mysterious bride, the Matronit, was also reckoned to be his sister. In the Jewish cult of the Cabbala God's dual male-female image was perpetuated. Meanwhile other sects perceived the Shekinah or Matronit as the female presence of God on Earth. The divine marital chamber was the sanctuary of the Jerusalem Temple, but from the moment the Temple was destroyed, the Matronit was destined to roam the Earth while the male aspect of Jehovah was left to rule the heavens alone." - Laurence Gardner, Bloodline of the Holy Grail, p. 18
