No, did the Assyrians or Babylonians worship Yahweh? Obviously not. The idea of there being multiple Gods, at odds with the other, is not foreign to the Bible.
Heraclitus (500 BC), is one of the first pagan men to provide an acceptable understanding of Logos (God) in the sense that the Church currently understands it, he even called it God.
Vatican I - The same Holy Mother Church holds and teaches that God, the beginning and end of all things, may be certainly known by the natural light of human reason, by means of created things; "for the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made" (Romans 1:20)
It does matter actually, because if those truths aren't arrived at naturally, then what you're actually dealing with is a form of social Darwinism where right and wrong are decided by the majority and/or the council of authorities according to some wavering higher idea in their religion. This was actually the ideology of Hitler as taught by the Yale Professor Timothy Snyder. This is also exactly what the Rabbis and Sheikhs believe, according to their own religions.
There's no such thing as imperfect Truth. You're either right or wrong. You can have an imperfect model of something, that only answers some questions and is wrong in other places, but that still means that you're wrong in totality.
Secondly, I reject that Islam or any other religion has any holiness at all whatsoever. Since the Council of Florence established that even a Christian, who shed his blood for Christ, had no share in salvation and automatically went to hell if he wasn't tied to the ecclesial body of the Catholic Church.
People are born into the truth in the sense that they can detect God, just by using reason alone. Its because of people like you and the people that you give allegiance to, that use these passive techniques of "evangelization", planting seeds in which not a soul has yet to see the root, that people like Sam Harris, Hitchens, Dawkins and every other sophist can work comfortably in destroying even what's left of any kind of cultural Christianity.
