MARRIAGE IS NOT A MAN-MADE TRADITION!
If marriage is not a man-made tradition than who invented marriage and don't say God. We have no empirical evidence on what God thinks or doesn't think about marriage.
The study of the tradition of marriage shows that marriage is a man-made or maybe I should say male-made tradition.
