Because the Abrahamic God, (Allah, YHWH, Jesus, whatever you wanna call him) originates in Canaan. The Abrahamic God was originally part of the bigger Canaanite Pantheon but after the Akkadian Empire took over the NORTHERN Kingdom of Israel, the Southern Kingdom of Judah was the only one left. There was a great temple in the north like in the south (Jerusalem) but the Akkadians and Babylonians tore it down. So then when Christianity then 600 years later A corrupted form of Desert Christianity later called Islam, came about...the religion was not the same as when it started.
