Immanuel
     Immanuel is an early focus if Isaiah's prophecy, and lends heavily to the Christ myth, but was he really Jesus?  To answer this, we must simply look at the prophecies concerning Immanuel.
     Isaiah 7:16, "For before the child shall know to refuse evil, and choose the good, the land that thou abhorests shall be forsaken of both her kings."  The "land that thou abhorest..."  refers to Damascus and Samaria, and the refuse evil/choose good reference is some point of Immanuel's development, possibly some rite of adulthood.
     The flaw in the Christians logic is that Damascus and Samaria fell to Assyria in 732 b.c.e., roughly 700 years before Jesus was born.
     Backing up just a bit, we now look at a mistranslation that leads many to assume Immanuel was Jesus.  Isaiah 7:14, "Therefore, the Lord himself shall give a sign; behold a Virgin shall conceive, and bear a son, and shall call his name Immanuel."
     The mistranslation here is the word "virgin".  The Hebrew word for virgin is "bethulah", but the mistranslated word is "almah", which means young woman, not virgin.  Had the Hebrew meant virgin, they would have used bethulah in Isaiah 7:14, instead they used almah
