Christianity didn't invent marriage. Who did? The gods? Which God? Who's God? Marriage is a religious thing and always has been. Which and how many ancient countries required a marriage license? Where were the records kept? If this was recorded by government we would have direct records of all lineage.
Maybe learn to read? .............Maybe write a coherent story? The state did not get into giving permission to marry until very recent times. Where did the state get the right to interfere in religion? NAMES, DATES, TIMES and PLACES please instead of your meandering and generalizations.
