Procreation isn't that Major reason of getting married but at least having someone whom you could confide on, share thoughts and feelings and ideas, but guess what?
What is the benefit of getting married without procreation then who takes over you or after you when you might have joined your ancestors? We see many people adopting a child or babies due to their inability to bear children,.or let say what if your parents didn't give birth to you what could have been of your existence today?
I'm not saying that humans should stop having children or that having children is wrong. Quite the opposite. My refusal to have children is a personal preference, and I'm not saying that those who aren't like me are wrong.
Marriage may be the only socially available means of living with a partner in one home. Keep in mind that I live in an Arab country whose culture doesn't permit extramarital relationships. Therefore, marriage is a means of living with a partner without social stigma.
Furthermore, marriage is not just a means of procreation. First, procreation can occur even without marriage, and second, the concept of marriage cannot be reduced to a mere channel for reproduction and the preservation of the lineage.
There is a philosophy called "antinatalism," which has many followers who believe that humans should stop procreating because the increasing human population threatens the stability of the entire planet. I'm familiar with it, but I don't share the same view. I don't oppose the idea of procreation in general, but I simply believe that planet Earth, in its current state, is uninhabitable due to the numerous crises caused by humans.
