ancestry

My ancestry by genealogy shows me coming from Scotland, Norway, and though many countries down passed the caspian sea into the land of the Jews. My DNA shows my ancestry as Spanish and Norwegian. I think when you go back to far the DNA no longer works. I do not think that DNA can tell if the native America have Jews blood or not for they came here a long time ago by the way of the Pacific Ocean and when you fallow the DNA that part agrees but time has goon on since the tower of babel and that blood has mixed with all the blood of anyone who has landed in the Americas from Asia or any were else. Abrahams ancestry is Asian, Before we say the Book of Mormon is false maybe we need to do some more study and see what is and isn't true about it. I understand that it may be in the language of the Mayans?
