And I think that Abraham was the father of Christianism, Islam and judaism.
Correct..and where as he had more then two is Irrelivant we are discuessing the first two.
Ishmael is the eldest so according to Israilite law he inharets his fathers position and land (what became Israil) Issac was the sacrifice that wasn't. The Muslims trace themselves back to Ishmael the Jews back to Issac. Ohe and chekc the dates Zoraster predated Abraham by a few centuries.
