"Because Africa is where we've found the oldest bones so far, that is where we THEORIZE life began. That theory can change based upon new evidence"

Yes, but so far, Africa is the oldest we have found. So untill new evidence is found of somewhere else, that is where it is.

And yet again. A Union between man woman, man man, woman woman has been around forever, even back before we evolved to humans.

But Marriage, non legal, religous, is religon. A Union, not called marriage, has always been around. But what you need to realize is that marriage itself was support to be religous, but recently it has become a more legal thing then religous. But it doesnt change the fact that a marriage is religous. A union of a sort, has been around forever. It is in the wording.

Marriage by definition is a religous cerimony. Now days, Marriage is becomming more legal. But the fact remains that Marriage is religous, and a union has been around forever. It is all in the wording of Marriage and Union. For example, a priest or some type of clergy performs a wedding, marriage. But a Union is performed by a Judge. You can be married and not make it legal. But a union is always non religous, and legal thing.
