God Almighty has created and designed this entire world through a specific system, which cannot be denied and ignored at any stage of life. If we don't act or behave according to the will of Allah, we can't lead a true and successful life. Your question that is marriage necessary to go through the activities of life can be answered in these terms.
Marriage is one of the activities imposed by God Almighty. A married person remains involved in his house, wife, children and other relations. He is very well aware that he will have to work hard to cope up his responsibilities in a nice manner. He also knows that he will have to take care the needs and demands of these relations as well. To achieve all these things he works, remains busy and involved round the clock. On the other hand the unmarried person has nothing to do with these responsibilities and he remains free. But his life has no goal and purpose and he bears a great deal of boredom. So we can say to lead a good and balanced life marriage is necessary to go through activities of life.
