What is marriage? For pro-creation of new babies to ensure mankind don't get extinct? If that is the goal then marriage is useless. Marriage is just a piece of paper to bind a couple to each other. If goal is to ensure mankind don't get extinct then man should have many many woman without any marriage burden to spread his seeds far and wide.

Therefore the definition of what is marriage is important. Pro-creation to ensure mankind don't get extinct is definitely not one of them.
