I've posted proof many times, however most people understand the scientific basis perfectly.
Please, specifically what is a lie?
I don't have to prove that your comment is a lie. You need to prove that it's true. Give us one a single legitimate social scientist who proves your "social science" claim.
Social science (and basic common sense) defines marriage as a legal union that meets the needs of two people.
It doesn't matter whether a couple marries to raise a family and/or for companionship and/or for one of the pair to improve their status (financial/material) and/or for love and/or lust/beauty...
All of these are legitimate reasons for marriage.
The government certainly doesn't become involved in the reasons people marry. It's none of their business. It's none of the church's business. And it's certainly none of your business.
