No, in fact the Muslim God isn't completely man made either. Their God started off as the same God as the Jews but their beliefs went off on a tangent later on. Much like the Mormons, Jehova's Witnesses etc. as well. The basis of these religious groups was originally the same but people misinterpreted the word of God and went off in their own direction.
